After this commit we can compile and run code with some limitations.
- The dlsym function is broken so this makes -run and bound checking
not work all the time. Make -k test does work for most code.
- You have to do:
ln -s /usr/lib/libN.so.x.y /usr/lib/libN.so
for all .so files in /usr/lib.
OpenBSD uses opendir/readdir to find the correct so file. This is
not the way other platforms do this.
Also the .a versions do not have all symbols that are present in the .so
files.
tcc.h:
- Use different dynamic loader
elf.h:
- Add SHT_X86_64_UNWIND
tccelf.c:
- Do not use -dl
- Add required NOTE section
- Add extra dynamic tags
- Allow SHT_X86_64_UNWIND/SHT_NOTE in tcc_load_object_file
tccrun.c:
- Uses MAP_FIXED because without the offset between exec and data section
becomes too big for x86_64
lib/bcheck.c:
- Do not use __libc_freeres
tests/tcctest.c:
- aligned_function also disabled for __GNUC__ == 4
