Can I push it to mob?
Did you test this? What happens if you enable this for
any structs
//#ifdef TCC_TARGET_ARM
//if (packed)
f->type.t |= VT_PACKED;
//#endif
and run the tests?
I did test this on arm32 openbsd. This is where the problem was.
However the above patch fails. I will provide a new patch.
I need to add support float/double/long double/pointers for this to work.
Btw, do we really need all these gen_increment_tcov ()'s?
Can't we just use the inc(0, TOK_INC) for all targets?
I did some measurements.
Compile tcc with itself 100 times with test coverage. (times in seconds):
function TOK_INC slowdown
x86_64 11.28 14.09 25%
i386 14.80 18.08 22%
arm32 233.53 415.94 78%
arm64 83.53 104.47 25%
riscv64 26.70 28.48 7% (qemu 10 times)
I did this because I saw a large slowdown.
The risc target is measured in qemu so not that reliable.
