games/libretro-beetle_psx built for armv7 uses its jit_arm*.c
code. The below is a simplification of the context for the
later shown build failure log file from the FreeBSD package
build servers:
# more libretro-beetle_psx_build_failure_reduction.c=20
extern float __addsf3(float, float);
extern double __adddf3(double, double);
int main()
{
(void)__addsf3(0, 0);
(void)__adddf3(0, 0);
}
# cc libretro-beetle_psx_build_failure_reduction.c
ld: error: undefined symbol: __addsf3
>>> referenced by libretro-beetle_psx_build_failure_reduction.c
>>> =
/tmp/libretro-beetle_psx_build_failure_reduction-e3ff6d.o:(main)
ld: error: undefined symbol: __adddf3
>>> referenced by libretro-beetle_psx_build_failure_reduction.c
>>> =
/tmp/libretro-beetle_psx_build_failure_reduction-e3ff6d.o:(main)
>>> did you mean: __adddi3
>>> defined in: /lib/libc.so.7
cc: error: linker command failed with exit code 1 (use -v to see =
invocation)
An recent example of the build failure on the FreeBSD package
builder servers is:
=
http://ampere2.nyi.freebsd.org/data/main-armv7-default/p85ef7d020401_s0fd8=
d3589/logs/errors/libretro-beetle_psx-0.20220211_1.log
There may be other examples than __addsf3 and __adddf3 (in
other software?). It seems there must not be a (complete)
test for the coverage of such things.
That same reduced-problem source (by content) builds for
aarch64 and runs fine on aarch64.
There are more issues with missing math routines vs. the lang/gcc*
code generation --on aarch64 as well. But the above sticks to
system-clang's toolchain as a context.
Note: I do not normally build games/libretro-beetle_psx and never
use it. I got here from looking into a somewhat analogous failure
and looking to find an official activity that was similar that I
could reference.
