Bug ID: 99941
Summary: m_ALDERLAKE is missing from m_CORE_AVX2
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
CC: crazylht at gmail dot com, lili.cui at intel dot com
Target Milestone: ---
Target: x86-64
i386-options.c has
#define m_ALDERLAKE (HOST_WIDE_INT_1U<<PROCESSOR_ALDERLAKE)
#define m_CORE_AVX512 (m_SKYLAKE_AVX512 | m_CANNONLAKE \
| m_ICELAKE_CLIENT | m_ICELAKE_SERVER | m_CASCADELAKE \
| m_TIGERLAKE | m_COOPERLAKE | m_SAPPHIRERAPIDS)
#define m_CORE_AVX2 (m_HASWELL | m_SKYLAKE | m_CORE_AVX512)
Should m_CORE_AVX2 include m_ALDERLAKE?

If we were more concerned about the performance of the big core, the answer
would be yes.

Let's adding m_ALDERLAKE to m_CORE_AVX2 first, if we want to do some balance
for small core and remove some tunes, we just need to mask off m_ALDERLAKE for
that specific tune.
