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 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# - indirect calls and jumps are not supported;
24#
25# Dual-ABI styling rules.
26#
27# 1. Adhere to Unix register and stack layout [see the end for
28# explanation].
29# 2. Forget about "red zone," stick to more traditional blended
30# stack frame allocation. If volatile storage is actually required
31# that is. If not, just leave the stack as is.
32# 3. Functions tagged with ".type name,@function" get crafted with
33# unified Win64 prologue and epilogue automatically. If you want
34# to take care of ABI differences yourself, tag functions as
35# ".type name,@abi-omnipotent" instead.
36# 4. To optimize the Win64 prologue you can specify number of input
37# arguments as ".type name,@function,N." Keep in mind that if N is
38# larger than 6, then you *have to* write "abi-omnipotent" code,
39# because >6 cases can't be addressed with unified prologue.
40# 5. Name local labels as .L*, do *not* use dynamic labels such as 1:
41# (sorry about latter).
42# 6. Don't use [or hand-code with .byte] "rep ret." "ret" mnemonic is
43# required to identify the spots, where to inject Win64 epilogue!
44# But on the pros, it's then prefixed with rep automatically:-)
45# 7. Due to MASM limitations [and certain general counter-intuitivity
46# of ip-relative addressing] generation of position-independent
47# code is assisted by synthetic directive, .picmeup, which puts
48# address of the *next* instruction into target register.
49#
50# Example 1:
51# .picmeup %rax
52# lea .Label-.(%rax),%rax
53# Example 2:
54# .picmeup %rcx
55# .Lpic_point:
56# ...
57# lea .Label-.Lpic_point(%rcx),%rbp

519# In Unix terms top of stack is argument transfer area for arguments
520# which could not be accomodated in registers. Or in other words 7th
521# [integer] argument resides at 8(%rsp) upon function entry point.
522# 128 bytes above %rsp constitute a "red zone" which is not touched
523# by signal handlers and can be used as temporal storage without
524# allocating a frame.
525#
526# In Win64 terms N*8 bytes on top of stack is argument transfer area,
527# which belongs to/can be overwritten by callee. N is the number of
528# arguments passed to callee, *but* not less than 4! This means that
529# upon function entry point 5th argument resides at 40(%rsp), as well
530# as that 32 bytes from 8(%rsp) can always be used as temporal
531# storage [without allocating a frame]. One can actually argue that
532# one can assume a "red zone" above stack pointer under Win64 as well.
533# Point is that at apparently no occasion Windows kernel would alter
534# the area above user stack pointer in true asynchronous manner...
535#
536# All the above means that if assembler programmer adheres to Unix
537# register and stack layout, but disregards the "red zone" existense,
538# it's possible to use following prologue and epilogue to "gear" from
