Bug ID: 103214
Summary: Incorrect function signatures for
__builtin_ia32_pblendd* instructions
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: web
Assignee: unassigned at gcc dot gnu.org
Reporter: gnugcc at bdwjn dot 33mail.com
Target Milestone: ---
The documentation on
https://gcc.gnu.org/onlinedocs/gcc/x86-Built-in-Functions.html lists the
following two AVX2 functions:
> v4si __builtin_ia32_pblendd128 (v4si,v4si)
> v8si __builtin_ia32_pblendd256 (v8si,v8si)
These instructions take two vectors and an integer mask, so this should be:
> v4si __builtin_ia32_pblendd128 (v4si,v4si,int)
> v8si __builtin_ia32_pblendd256 (v8si,v8si,int)
