Bug ID: 70738
Summary: Add -minteger-only option
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
CC: kirill.yukhin at intel dot com, ubizjak at gmail dot com
Target Milestone: ---
Target: x86
X86 Linux kernel is compiled only with integer instructions. Currently,
-mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -mno-80387 -mno-fp-ret-in-387
-mskip-rax-setup
is used to compile kernel. If we add another non-integer feature, it
has to be turned off. We can add a -minteger-only option to disable
all non-integer features so that kernel doesn't need a long list and
the same option will work for future compilers.
