Hi guys,
Testing mod show that ARM and Aarch64 are broken differently. I'm reluctant to
test it only Windows as it will break my Lisp development toolchain.
Hi Christian,
there are two things basically you could do. First in tests/Makefile:78
you could try adding $(NATIVE_DEFINES):
@echo ------------ $@ ------------
./libtcc_tes$*$(EXESUF) $(TCCFLAGS) $(NATIVE_DEFINES) <-----
Second is at tcc.h:150, if you want to you could tweak the default
settings for these architectures. The bits there are meant basically
to make compiling tcc as simple as if it were a hello-world program
(which it is after all, or close to):
gcc tcc.c -o tcc
Therefor, if you think that your system configuration is somehow
"default", then you have my full okay to add the two or three lines
each there to get such simplicity as a feature. ;)
(Maybe TCC_ARM_VFP and/or CONFIG_TRIPLET and/or whatever you see
on the gcc command from make.) To see whether it really works you
would need to run two stages:
gcc tcc.c -o tcc && ./tcc -B. tcc.c -o tcc1
If you did install tcc previously, -B. may be omitted too.
As to 'usleep' and 'gettimeofday', maybe it needs unistd.h or time.h or
maybe sys/time.h. I see your gcc suggests to use 'fseek' instead of
'usleep'. That is interesting.
Thanks,
