I was not able to find any test cases for these named builtins. I
fixed the other issues you mentioned in the message and patch below.
Carl Love
----------------------------------------------
GCC maintainers:
The defines for vec_popcnt, vec_popcnth, vec_popcntw, vec_popcntd in
gcc/config/rs6000/altivec.h are not listed in the Power 64-Bi ELF V2
ABI specification revision 1.4, May 10, 2017. They are not used by any
of the regression tests. They also do not work as reported in PR
85830.
The following patch removes the unsupported defines for the builtin
functions.
The patch has been tested on
powerpc64le-unknown-linux-gnu (Power 9 LE
with no regression errors.
Please let me know if this patch is acceptable for mainline.
