1The perl scripts in this directory are my 'hack' to generate
2multiple different assembler formats via the one origional script.
3
4The way to use this library is to start with adding the path to this directory
5and then include it.
6
7push(@INC,"perlasm","../../perlasm");
8require "x86asm.pl";
9
10The first thing we do is setup the file and type of assember
11
12&asm_init($ARGV[0],$0);
13
14The first argument is the 'type'. Currently
15'cpp', 'sol', 'a.out', 'elf' or 'win32'.
16Argument 2 is the file name.
17
18The reciprocal function is
19&asm_finish() which should be called at the end.
20
21There are 2 main 'packages'. x86ms.pl, which is the microsoft assembler,
22and x86unix.pl which is the unix (gas) version.
23
24Functions of interest are:
25&external_label("des_SPtrans"); declare and external variable
26&LB(reg); Low byte for a register
27&HB(reg); High byte for a register
28&BP(off,base,index,scale) Byte pointer addressing
29&DWP(off,base,index,scale) Word pointer addressing
30&stack_push(num) Basically a 'sub esp, num*4' with extra
31&stack_pop(num) inverse of stack_push
32&function_begin(name,extra) Start a function with pushing of
33 edi, esi, ebx and ebp. extra is extra win32
34 external info that may be required.
35&function_begin_B(name,extra) Same as norma function_begin but no pushing.
36&function_end(name) Call at end of function.
37&function_end_A(name) Standard pop and ret, for use inside functions
38&function_end_B(name) Call at end but with poping or 'ret'.
39&swtmp(num) Address on stack temp word.
40&wparam(num) Parameter number num, that was push
41 in C convention. This all works over pushes
42 and pops.
43&comment("hello there") Put in a comment.
44&label("loop") Refer to a label, normally a jmp target.
45&set_label("loop") Set a label at this point.
46&data_word(word) Put in a word of data.
47
48So how does this all hold together? Given
49
50int calc(int len, int *data)
51 {
52 int i,j=0;
53
54 for (i=0; i<len; i++)
55 {
56 j+=other(data[i]);
57 }
58 }
59
60So a very simple version of this function could be coded as
61
62 push(@INC,"perlasm","../../perlasm");
63 require "x86asm.pl";
64
65 &asm_init($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
99The above example is very very unoptimised but gives an idea of how
100things work.
101
102There 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
114So for example, given
115void BF_encrypt(BF_LONG *data,BF_KEY *key);
116void BF_decrypt(BF_LONG *data,BF_KEY *key);
117void 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

761# Win64 SEH, Structured Exception Handling.
762#
763# Unlike on Unix systems(*) lack of Win64 stack unwinding information
764# has undesired side-effect at run-time: if an exception is raised in
765# assembler subroutine such as those in question (basically we're
766# referring to segmentation violations caused by malformed input
767# parameters), the application is briskly terminated without invoking
768# any exception handlers, most notably without generating memory dump
769# or any user notification whatsoever. This poses a problem. It's
770# possible to address it by registering custom language-specific
771# handler that would restore processor context to the state at
772# subroutine entry point and return "exception is not handled, keep
773# unwinding" code. Writing such handler can be a challenge... But it's
774# doable, though requires certain coding convention. Consider following
775# snippet:
776#
777# .type function,@function
778# function:
779# movq %rsp,%rax # copy rsp to volatile register
780# pushq %r15 # save non-volatile registers
781# pushq %rbx
782# pushq %rbp
783# movq %rsp,%r11
784# subq %rdi,%r11 # prepare [variable] stack frame
785# andq $-64,%r11
786# movq %rax,0(%r11) # check for exceptions
787# movq %r11,%rsp # allocate [variable] stack frame
788# movq %rax,0(%rsp) # save original rsp value
789# magic_point:
790# ...
791# movq 0(%rsp),%rcx # pull original rsp value
792# movq -24(%rcx),%rbp # restore non-volatile registers
793# movq -16(%rcx),%rbx
794# movq -8(%rcx),%r15
795# movq %rcx,%rsp # restore original rsp
796# ret
797# .size function,.-function
798#
799# The key is that up to magic_point copy of original rsp value remains
800# in chosen volatile register and no non-volatile register, except for
801# rsp, is modified. While past magic_point rsp remains constant till
802# the very end of the function. In this case custom language-specific
803# exception handler would look like this:
804#
805# EXCEPTION_DISPOSITION handler (EXCEPTION_RECORD *rec,ULONG64 frame,
806# CONTEXT *context,DISPATCHER_CONTEXT *disp)
807# { ULONG64 *rsp = (ULONG64 *)context->Rax;
808# if (context->Rip >= magic_point)
809# { rsp = ((ULONG64 **)context->Rsp)[0];
810# context->Rbp = rsp[-3];
811# context->Rbx = rsp[-2];
812# context->R15 = rsp[-1];
813# }
814# context->Rsp = (ULONG64)rsp;
815# context->Rdi = rsp[1];
816# context->Rsi = rsp[2];
817#
818# memcpy (disp->ContextRecord,context,sizeof(CONTEXT));
819# RtlVirtualUnwind(UNW_FLAG_NHANDLER,disp->ImageBase,
820# dips->ControlPc,disp->FunctionEntry,disp->ContextRecord,
821# &disp->HandlerData,&disp->EstablisherFrame,NULL);
822# return ExceptionContinueSearch;
823# }
824#
825# It's appropriate to implement this handler in assembler, directly in
826# function's module. In order to do that one has to know members'
827# offsets in CONTEXT and DISPATCHER_CONTEXT structures and some constant
828# values. Here they are:
829#
830# CONTEXT.Rax 120
831# CONTEXT.Rcx 128
832# CONTEXT.Rdx 136
833# CONTEXT.Rbx 144
834# CONTEXT.Rsp 152
835# CONTEXT.Rbp 160

841# CONTEXT.R11 208
842# CONTEXT.R12 216
843# CONTEXT.R13 224
844# CONTEXT.R14 232
845# CONTEXT.R15 240
846# CONTEXT.Rip 248
847# CONTEXT.Xmm6 512
848# sizeof(CONTEXT) 1232
849# DISPATCHER_CONTEXT.ControlPc 0
850# DISPATCHER_CONTEXT.ImageBase 8
851# DISPATCHER_CONTEXT.FunctionEntry 16
852# DISPATCHER_CONTEXT.EstablisherFrame 24
853# DISPATCHER_CONTEXT.TargetIp 32
854# DISPATCHER_CONTEXT.ContextRecord 40
855# DISPATCHER_CONTEXT.LanguageHandler 48
856# DISPATCHER_CONTEXT.HandlerData 56
857# UNW_FLAG_NHANDLER 0
858# ExceptionContinueSearch 1
859#
860# In order to tie the handler to the function one has to compose
861# couple of structures: one for .xdata segment and one for .pdata.
862#
863# UNWIND_INFO structure for .xdata segment would be
864#
865# function_unwind_info:
866# .byte 9,0,0,0
867# .rva handler
868#
869# This structure designates exception handler for a function with
870# zero-length prologue, no stack frame or frame register.
871#
872# To facilitate composing of .pdata structures, auto-generated "gear"
873# prologue copies rsp value to rax and denotes next instruction with
874# .LSEH_begin_{function_name} label. This essentially defines the SEH
875# styling rule mentioned in the beginning. Position of this label is
876# chosen in such manner that possible exceptions raised in the "gear"
877# prologue would be accounted to caller and unwound from latter's frame.
878# End of function is marked with respective .LSEH_end_{function_name}
879# label. To summarize, .pdata segment would contain
880#
881# .rva .LSEH_begin_function
882# .rva .LSEH_end_function
883# .rva function_unwind_info
884#
885# Reference to functon_unwind_info from .xdata segment is the anchor.
886# In case you wonder why references are 32-bit .rvas and not 64-bit
887# .quads. References put into these two segments are required to be
888# *relative* to the base address of the current binary module, a.k.a.
889# image base. No Win64 module, be it .exe or .dll, can be larger than
890# 2GB and thus such relative references can be and are accommodated in
891# 32 bits.
892#
893# Having reviewed the example function code, one can argue that "movq
894# %rsp,%rax" above is redundant. It is not! Keep in mind that on Unix
895# rax would contain an undefined value. If this "offends" you, use
896# another register and refrain from modifying rax till magic_point is
897# reached, i.e. as if it was a non-volatile register. If more registers
898# are required prior [variable] frame setup is completed, note that
899# nobody says that you can have only one "magic point." You can
900# "liberate" non-volatile registers by denoting last stack off-load
901# instruction and reflecting it in finer grade unwind logic in handler.
902# After all, isn't it why it's called *language-specific* handler...
903#
904# Attentive reader can notice that exceptions would be mishandled in
905# auto-generated "gear" epilogue. Well, exception effectively can't
906# occur there, because if memory area used by it was subject to
907# segmentation violation, then it would be raised upon call to the
908# function (and as already mentioned be accounted to caller, which is
909# not a problem). If you're still not comfortable, then define tail
910# "magic point" just prior ret instruction and have handler treat it...
911#
912# (*) Note that we're talking about run-time, not debug-time. Lack of
913# unwind information makes debugging hard on both Windows and
914# Unix. "Unlike" referes to the fact that on Unix signal handler
915# will always be invoked, core dumped and appropriate exit code
916# returned to parent (for user notification).
