-dhalf-assemble -fabi=ms -fdebug-stack-size=0 -fcmodel=large

If this parameter is added, the test examples that get the correct results in the previous compilation cannot get the correct results Has the work behind this parameter been completed?

-dhalf-assemble is still work in progress, and should not really be used. Its purpose is to allow me to more easily implement the assembler. It works by replacing some instructions with the corresponding byte-code. For example movl -28(%rbp), %edi is replaced with .byte 0x8b, 0x7d, 0xe4.

In which way does it not give the correct results? On my system all tests pass with it activated.

[icyfox168168]

Different results are obtained in an MD5 algorithm

test. C file I send you email

char decrypt[16] ={0};

printf("gg %02x %d \n",decrypt[0],str_len1("88"));

MD5_CTX md5;
MD5Init(&md5);
MD5Update(&md5, "88", str_len1("88"));
MD5Final(&md5, decrypt);

printf("ff %02x %d \n",decrypt[0],str_len1("88"));

cc.exe test.c -fabi=ms -fdebug-stack-size=0 -fcmodel=large -D test.s -IC:\Users\fix\Desktop\C-Compiler-Test\include gg 00 2 ff 2a 2 ret 24

cc.exe test.c -dhalf-assemble -fabi=ms -fdebug-stack-size=0 -fcmodel=large -D test0.s -IC:\Users\fix\Desktop\C-Compiler-Test\include gg 00 2 ff ffffff90 2 ret 23

The latest version solves the problem

gg 00 2 ff 2a 2 ret 24

compiler bddisasm

[lasarus]

I'm not able to reproduce that bug. bddisasm with the example provided in their README.md compiles on my system. In which source file does the error occur?

[lasarus]

I have found the error. It should work with the latest master

[icyfox168168]

bddisasm\bdshemu\bdshemu.c

bddisasm\bdshemu\bdshemu.c -dhalf-assemble -fabi=ms -fdebug-stack-size=20480 -fcmodel=large -D bdshemu.s -fmingw-workarounds

Internal compiler error on line 180 file src/assembler/assembler.c of compiler source: "Could not assemble cmpl"

[icyfox168168]

Without -dhalf-assemble everything works fine

[lasarus]

It should be fixed now.

[icyfox168168]

ok

[icyfox168168]

Internal compiler error on line 161 file src/assembler/assembler.c of compiler source: "Could not assemble testw 1 1 0 0"

[lasarus]

Encoding for testw was added in latest commit. Since -dhalf-assemble no longer exists, I will close this issue.
