Bug ID: 65849
Summary: Add missing tuning knobs to #pragma target/attribute
target support
Product: gcc
Version: 5.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Host: powerpc64-unknown-linux-gnu
Target: powerpc64-unknown-linux-gnu
Build: powerpc64-unknown-linux-gnu
Some of the -m<option> tuning knobs were not allowed for #pragma target "..."
and attribute ((target("...))) support. At first glance, we should add support
for -m{,no-}save-toc-indirect, -m{,no-}optimize-swaps,
-m{,no-}upper-regs-{sf,df}.
Options that affect the ABI (like -mpointers-to-nested-functions, -mabi=...,
-mlittle, -m32, etc.) should not be added, but where possible the other options
should be added.
