- tcc_add_linker_symbols():
don't add for dlls
- bind_exe_dynsym():
update _end symbol when done
allow data definition in the .so override a bss symbol
in the exe. For example
exe: int x;
.so: int x = 123;
- set_elf_sym():
cannot compare section numbers with symbols from dlls
tcc_load_obj():
return -1 from symbol conflict errors
tests/tests2/148_linker_symbols:
- use only one file
- make it print useful output rather than just "2 errors."
In general, the tests2 setup with .expect files is meant
to compare text output. For example:
printf("val = %d\n", val);
.expect file can be generated or refreshed using
make tests2.nnn+
or in order to force generation with tcc itself
make tests2.nnn+ GEN-CC='$(GEN-TCC)'
tccgen.c:
- __attribute__((section(...))) : set section type/flags
according to first usage
- fix bcheck bounds for -fcommon
