Hello list, jiang,
I tried to "fix" the issue that I mentioned in previous mail, which consists of:
diff --git a/i386-gen.c b/i386-gen.c
index b9811f5..7a9bde1 100644

tcc compiles but for sanity check I recompile tcc by itself, which
generates illegel instructions in libcrt:
(gdb) r
Starting program: D:\tinycc\tcc.exe -B../win32 -I../include -c
libcrt.c -o i386-win32/libcrt.o -g -I.. -O2 -DTCC_TARGET_I386
-DTCC_TARGET_PE
[New Thread 5452.0x108c]
Program received signal SIGILL, Illegal instruction.
0x0042e54d in __ashldi3 () at libcrt.c:477
477 return u.ll;
(gdb)
Advise needed for further actions. Thanks.
Regards,
Roy
