Bug ID: 111645
Summary: Intrinsics vec_sldb /vec_srdb fail with __vector
unsigned __int128
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

example of the problem. Compile with gcc -m64 -O3 -mcpu=power10 -c sldbi.c
GCC 12 and 13 fail to compile vector intrisic vec_sldb / vec_srdb as required
by the Power Vector Intrinsic Programming Reference.
error: invalid parameter combination for AltiVec intrinsic ‘__builtin_vec_sldb’
Both the Programming Reference and the GCC documentation state that vector
(unsigned/signed) __int128 are valid operands. But they fail with a
error: invalid parameter combination for AltiVec intrinsic ‘__builtin_vec_sldb’
or
error: invalid parameter combination for AltiVec intrinsic ‘__builtin_vec_srdb’
