| 1 | The perl scripts in this directory are my 'hack' to generate | ||
| 2 | multiple different assembler formats via the one origional script. | ||
| 3 | |||
| 4 | The way to use this library is to start with adding the path to this directory | ||
| 5 | and then include it. | ||
| 6 | |||
| 7 | push(@INC,"perlasm","../../perlasm"); | ||
| 8 | require "x86asm.pl"; | ||
| 9 | |||
| 10 | The first thing we do is setup the file and type of assember | ||
| 11 | |||
| 12 | &asm_init($ARGV[0],$0); | ||
| 13 | |||
| 14 | The first argument is the 'type'. Currently | ||
| 15 | 'cpp', 'sol', 'a.out', 'elf' or 'win32'. | ||
| 16 | Argument 2 is the file name. | ||
| 17 | |||
| 18 | The reciprocal function is | ||
| 19 | &asm_finish() which should be called at the end. | ||
| 20 | |||
| 21 | There are 2 main 'packages'. x86ms.pl, which is the microsoft assembler, | ||
| 22 | and x86unix.pl which is the unix (gas) version. | ||
| 23 | |||
| 24 | Functions of interest are: | ||
| 25 | &external_label("des_SPtrans"); declare and external variable | ||
| 26 | &LB(reg); Low byte for a register | ||
| 27 | &HB(reg); High byte for a register | ||
| 28 | &BP(off,base,index,scale) Byte pointer addressing | ||
| 29 | &DWP(off,base,index,scale) Word pointer addressing | ||
| 30 | &stack_push(num) Basically a 'sub esp, num*4' with extra | ||
| 31 | &stack_pop(num) inverse of stack_push | ||
| 32 | &function_begin(name,extra) Start a function with pushing of | ||
| 33 | edi, esi, ebx and ebp. extra is extra win32 | ||
| 34 | external info that may be required. | ||
| 35 | &function_begin_B(name,extra) Same as norma function_begin but no pushing. | ||
| 36 | &function_end(name) Call at end of function. | ||
| 37 | &function_end_A(name) Standard pop and ret, for use inside functions | ||
| 38 | &function_end_B(name) Call at end but with poping or 'ret'. | ||
| 39 | &swtmp(num) Address on stack temp word. | ||
| 40 | &wparam(num) Parameter number num, that was push | ||
| 41 | in C convention. This all works over pushes | ||
| 42 | and pops. | ||
| 43 | &comment("hello there") Put in a comment. | ||
| 44 | &label("loop") Refer to a label, normally a jmp target. | ||
| 45 | &set_label("loop") Set a label at this point. | ||
| 46 | &data_word(word) Put in a word of data. | ||
| 47 | |||
| 48 | So how does this all hold together? Given | ||
| 49 | |||
| 50 | int calc(int len, int *data) | ||
| 51 | { | ||
| 52 | int i,j=0; | ||
| 53 | |||
| 54 | for (i=0; i<len; i++) | ||
| 55 | { | ||
| 56 | j+=other(data[i]); | ||
| 57 | } | ||
| 58 | } | ||
| 59 | |||
| 60 | So a very simple version of this function could be coded as | ||
| 61 | |||
| 62 | push(@INC,"perlasm","../../perlasm"); | ||
| 63 | require "x86asm.pl"; | ||
| 64 | |||
| 65 | &asm_init($ARGV[0],"cacl.pl"); | ||
| 66 | |||
| 67 | &external_label("other"); | ||
| 68 | |||
| 69 | $tmp1= "eax"; | ||
| 70 | $j= "edi"; | ||
| 71 | $data= "esi"; | ||
| 72 | $i= "ebp"; | ||
| 73 | |||
| 74 | &comment("a simple function"); | ||
| 75 | &function_begin("calc"); | ||
| 76 | &mov( $data, &wparam(1)); # data | ||
| 77 | &xor( $j, $j); | ||
| 78 | &xor( $i, $i); | ||
| 79 | |||
| 80 | &set_label("loop"); | ||
| 81 | &cmp( $i, &wparam(0)); | ||
| 82 | &jge( &label("end")); | ||
| 83 | |||
| 84 | &mov( $tmp1, &DWP(0,$data,$i,4)); | ||
| 85 | &push( $tmp1); | ||
| 86 | &call( "other"); | ||
| 87 | &add( $j, "eax"); | ||
| 88 | &pop( $tmp1); | ||
| 89 | &inc( $i); | ||
| 90 | &jmp( &label("loop")); | ||
| 91 | |||
| 92 | &set_label("end"); | ||
| 93 | &mov( "eax", $j); | ||
| 94 | |||
| 95 | &function_end("calc"); | ||
| 96 | |||
| 97 | &asm_finish(); | ||
| 98 | |||
| 99 | The above example is very very unoptimised but gives an idea of how | ||
| 100 | things work. | ||
| 101 | |||
| 102 | There is also a cbc mode function generator in cbc.pl | ||
| 103 | |||
| 104 | &cbc( $name, | ||
| 105 | $encrypt_function_name, | ||
| 106 | $decrypt_function_name, | ||
| 107 | $true_if_byte_swap_needed, | ||
| 108 | $parameter_number_for_iv, | ||
| 109 | $parameter_number_for_encrypt_flag, | ||
| 110 | $first_parameter_to_pass, | ||
| 111 | $second_parameter_to_pass, | ||
| 112 | $third_parameter_to_pass); | ||
| 113 | |||
| 114 | So for example, given | ||
| 115 | void BF_encrypt(BF_LONG *data,BF_KEY *key); | ||
| 116 | void BF_decrypt(BF_LONG *data,BF_KEY *key); | ||
| 117 | void BF_cbc_encrypt(unsigned char *in, unsigned char *out, long length, | ||
| 118 | BF_KEY *ks, unsigned char *iv, int enc); | ||
| 119 | |||
| 120 | &cbc("BF_cbc_encrypt","BF_encrypt","BF_encrypt",1,4,5,3,-1,-1); | ||
| 121 | |||
| 122 | &cbc("des_ncbc_encrypt","des_encrypt","des_encrypt",0,4,5,3,5,-1); | ||
| 123 | &cbc("des_ede3_cbc_encrypt","des_encrypt3","des_decrypt3",0,6,7,3,4,5); | ||

| 3 | # Ascetic x86_64 AT&T to MASM/NASM assembler translator by <appro>. | ||
| 4 | # | ||
| 5 | # Why AT&T to MASM and not vice versa? Several reasons. Because AT&T | ||
| 6 | # format is way easier to parse. Because it's simpler to "gear" from | ||
| 7 | # Unix ABI to Windows one [see cross-reference "card" at the end of | ||
| 8 | # file]. Because Linux targets were available first... | ||
| 9 | # | ||
| 10 | # In addition the script also "distills" code suitable for GNU | ||
| 11 | # assembler, so that it can be compiled with more rigid assemblers, | ||
| 12 | # such as Solaris /usr/ccs/bin/as. | ||
| 13 | # | ||
| 14 | # This translator is not designed to convert *arbitrary* assembler | ||
| 15 | # code from AT&T format to MASM one. It's designed to convert just | ||
| 16 | # enough to provide for dual-ABI OpenSSL modules development... | ||
| 17 | # There *are* limitations and you might have to modify your assembler | ||
| 18 | # code or this script to achieve the desired result... | ||
| 19 | # | ||
| 20 | # Currently recognized limitations: | ||
| 21 | # | ||
| 22 | # - can't use multiple ops per line; | ||
| 23 | # | ||
| 24 | # Dual-ABI styling rules. | ||
| 25 | # | ||
| 26 | # 1. Adhere to Unix register and stack layout [see cross-reference | ||
| 27 | # ABI "card" at the end for explanation]. | ||
| 28 | # 2. Forget about "red zone," stick to more traditional blended | ||
| 29 | # stack frame allocation. If volatile storage is actually required | ||
| 30 | # that is. If not, just leave the stack as is. | ||
| 31 | # 3. Functions tagged with ".type name,@function" get crafted with | ||
| 32 | # unified Win64 prologue and epilogue automatically. If you want | ||
| 33 | # to take care of ABI differences yourself, tag functions as | ||
| 34 | # ".type name,@abi-omnipotent" instead. | ||
| 35 | # 4. To optimize the Win64 prologue you can specify number of input | ||
| 36 | # arguments as ".type name,@function,N." Keep in mind that if N is | ||
| 37 | # larger than 6, then you *have to* write "abi-omnipotent" code, | ||
| 38 | # because >6 cases can't be addressed with unified prologue. | ||
| 39 | # 5. Name local labels as .L*, do *not* use dynamic labels such as 1: | ||
| 40 | # (sorry about latter). | ||
| 41 | # 6. Don't use [or hand-code with .byte] "rep ret." "ret" mnemonic is | ||
| 42 | # required to identify the spots, where to inject Win64 epilogue! | ||
| 43 | # But on the pros, it's then prefixed with rep automatically:-) | ||
| 44 | # 7. Stick to explicit ip-relative addressing. If you have to use | ||
| 45 | # GOTPCREL addressing, stick to mov symbol@GOTPCREL(%rip),%r??. | ||
| 46 | # Both are recognized and translated to proper Win64 addressing | ||
| 47 | # modes. To support legacy code a synthetic directive, .picmeup, | ||
| 48 | # is implemented. It puts address of the *next* instruction into | ||
| 49 | # target register, e.g.: | ||
| 50 | # | ||
| 51 | # .picmeup %rax | ||
| 52 | # lea .Label-.(%rax),%rax | ||
| 53 | # | ||
| 54 | # 8. In order to provide for structured exception handling unified | ||
| 55 | # Win64 prologue copies %rsp value to %rax. For further details | ||
| 56 | # see SEH paragraph at the end. | ||
| 57 | # 9. .init segment is allowed to contain calls to functions only. | ||
| 58 | # a. If function accepts more than 4 arguments *and* >4th argument | ||
| 59 | # is declared as non 64-bit value, do clear its upper part. | ||

| 765 | # Win64 SEH, Structured Exception Handling. | ||
| 766 | # | ||
| 767 | # Unlike on Unix systems(*) lack of Win64 stack unwinding information | ||
| 768 | # has undesired side-effect at run-time: if an exception is raised in | ||
| 769 | # assembler subroutine such as those in question (basically we're | ||
| 770 | # referring to segmentation violations caused by malformed input | ||
| 771 | # parameters), the application is briskly terminated without invoking | ||
| 772 | # any exception handlers, most notably without generating memory dump | ||
| 773 | # or any user notification whatsoever. This poses a problem. It's | ||
| 774 | # possible to address it by registering custom language-specific | ||
| 775 | # handler that would restore processor context to the state at | ||
| 776 | # subroutine entry point and return "exception is not handled, keep | ||
| 777 | # unwinding" code. Writing such handler can be a challenge... But it's | ||
| 778 | # doable, though requires certain coding convention. Consider following | ||
| 779 | # snippet: | ||
| 780 | # | ||
| 781 | # .type function,@function | ||
| 782 | # function: | ||
| 783 | # movq %rsp,%rax # copy rsp to volatile register | ||
| 784 | # pushq %r15 # save non-volatile registers | ||
| 785 | # pushq %rbx | ||
| 786 | # pushq %rbp | ||
| 787 | # movq %rsp,%r11 | ||
| 788 | # subq %rdi,%r11 # prepare [variable] stack frame | ||
| 789 | # andq $-64,%r11 | ||
| 790 | # movq %rax,0(%r11) # check for exceptions | ||
| 791 | # movq %r11,%rsp # allocate [variable] stack frame | ||
| 792 | # movq %rax,0(%rsp) # save original rsp value | ||
| 793 | # magic_point: | ||
| 794 | # ... | ||
| 795 | # movq 0(%rsp),%rcx # pull original rsp value | ||
| 796 | # movq -24(%rcx),%rbp # restore non-volatile registers | ||
| 797 | # movq -16(%rcx),%rbx | ||
| 798 | # movq -8(%rcx),%r15 | ||

| 800 | # ret | ||
| 801 | # .size function,.-function | ||
| 802 | # | ||
| 803 | # The key is that up to magic_point copy of original rsp value remains | ||
| 804 | # in chosen volatile register and no non-volatile register, except for | ||
| 805 | # rsp, is modified. While past magic_point rsp remains constant till | ||
| 806 | # the very end of the function. In this case custom language-specific | ||
| 807 | # exception handler would look like this: | ||
| 808 | # | ||
| 809 | # EXCEPTION_DISPOSITION handler (EXCEPTION_RECORD *rec,ULONG64 frame, | ||
| 810 | # CONTEXT *context,DISPATCHER_CONTEXT *disp) | ||
| 811 | # { ULONG64 *rsp = (ULONG64 *)context->Rax; | ||
| 812 | # if (context->Rip >= magic_point) | ||
| 813 | # { rsp = ((ULONG64 **)context->Rsp)[0]; | ||
| 814 | # context->Rbp = rsp[-3]; | ||
| 815 | # context->Rbx = rsp[-2]; | ||
| 816 | # context->R15 = rsp[-1]; | ||
| 817 | # } | ||
| 818 | # context->Rsp = (ULONG64)rsp; | ||
| 819 | # context->Rdi = rsp[1]; | ||
| 820 | # context->Rsi = rsp[2]; | ||
| 821 | # | ||
| 822 | # memcpy (disp->ContextRecord,context,sizeof(CONTEXT)); | ||
| 823 | # RtlVirtualUnwind(UNW_FLAG_NHANDLER,disp->ImageBase, | ||
| 824 | # dips->ControlPc,disp->FunctionEntry,disp->ContextRecord, | ||

| 826 | # return ExceptionContinueSearch; | ||
| 827 | # } | ||
| 828 | # | ||
| 829 | # It's appropriate to implement this handler in assembler, directly in | ||
| 830 | # function's module. In order to do that one has to know members' | ||

| 863 | # | ||
| 864 | # In order to tie the handler to the function one has to compose | ||
| 865 | # couple of structures: one for .xdata segment and one for .pdata. | ||
| 866 | # | ||
| 867 | # UNWIND_INFO structure for .xdata segment would be | ||
| 868 | # | ||
| 869 | # function_unwind_info: | ||
| 870 | # .byte 9,0,0,0 | ||
| 871 | # .rva handler | ||
| 872 | # | ||
| 873 | # This structure designates exception handler for a function with | ||
| 874 | # zero-length prologue, no stack frame or frame register. | ||
| 875 | # | ||
| 876 | # To facilitate composing of .pdata structures, auto-generated "gear" | ||
| 877 | # prologue copies rsp value to rax and denotes next instruction with | ||
| 878 | # .LSEH_begin_{function_name} label. This essentially defines the SEH | ||
| 879 | # styling rule mentioned in the beginning. Position of this label is | ||
| 880 | # chosen in such manner that possible exceptions raised in the "gear" | ||
| 881 | # prologue would be accounted to caller and unwound from latter's frame. | ||
| 882 | # End of function is marked with respective .LSEH_end_{function_name} | ||
| 883 | # label. To summarize, .pdata segment would contain | ||
| 884 | # | ||
| 885 | # .rva .LSEH_begin_function | ||
| 886 | # .rva .LSEH_end_function | ||
| 887 | # .rva function_unwind_info | ||
| 888 | # | ||
| 889 | # Reference to functon_unwind_info from .xdata segment is the anchor. | ||
| 890 | # In case you wonder why references are 32-bit .rvas and not 64-bit | ||
| 891 | # .quads. References put into these two segments are required to be | ||
| 892 | # *relative* to the base address of the current binary module, a.k.a. | ||
| 893 | # image base. No Win64 module, be it .exe or .dll, can be larger than | ||
| 894 | # 2GB and thus such relative references can be and are accommodated in | ||
| 895 | # 32 bits. | ||
| 896 | # | ||
| 897 | # Having reviewed the example function code, one can argue that "movq | ||
| 898 | # %rsp,%rax" above is redundant. It is not! Keep in mind that on Unix | ||
| 899 | # rax would contain an undefined value. If this "offends" you, use | ||
| 900 | # another register and refrain from modifying rax till magic_point is | ||
| 901 | # reached, i.e. as if it was a non-volatile register. If more registers | ||
| 902 | # are required prior [variable] frame setup is completed, note that | ||
| 903 | # nobody says that you can have only one "magic point." You can | ||
| 904 | # "liberate" non-volatile registers by denoting last stack off-load | ||
| 905 | # instruction and reflecting it in finer grade unwind logic in handler. | ||
| 906 | # After all, isn't it why it's called *language-specific* handler... | ||
| 907 | # | ||
| 908 | # Attentive reader can notice that exceptions would be mishandled in | ||
| 909 | # auto-generated "gear" epilogue. Well, exception effectively can't | ||
| 910 | # occur there, because if memory area used by it was subject to | ||
| 911 | # segmentation violation, then it would be raised upon call to the | ||
| 912 | # function (and as already mentioned be accounted to caller, which is | ||
| 913 | # not a problem). If you're still not comfortable, then define tail | ||
| 914 | # "magic point" just prior ret instruction and have handler treat it... | ||
| 915 | # | ||
| 916 | # (*) Note that we're talking about run-time, not debug-time. Lack of | ||
| 917 | # unwind information makes debugging hard on both Windows and | ||
| 918 | # Unix. "Unlike" referes to the fact that on Unix signal handler | ||
| 919 | # will always be invoked, core dumped and appropriate exit code | ||
| 920 | # returned to parent (for user notification). | ||
