Hi,
After this commit:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=a98dd536b1017c2b814a3465206c6c01b2890998
I am no longer able to see mkoffload (and accel compiler) being invoked for
nvptx (-save-temps also doesn't show accel dumps).
I have attached -v output before and after the commit for x86_64->nvptx
offloading for the following simple test (host doesn't really matter, can also
reproduce with aarch64 host):
int main()
{
int x = 1;
#pragma omp target map(x)
x = 5;
return x;
}
Thanks,
Prathamesh
