Bug ID: 116836
Summary: [SH] Unknown FPU mode switch state for inline-asm
blocks
Product: gcc
Version: 14.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: olegendo at gcc dot gnu.org
Target Milestone: ---
Currently the FPU mode-switching does not take into account inline-asm blocks.
As a result it's difficult to make sure that the FPU is in a known particular
state when it his the inline-asm blocks. It makes inline-asm cumbersome to
use, in particular with LTO, which can automatically inline functions and break
the FPU mode assumptions at function entry. What people are currently doing is
forcing those functions to be no-inline to avoid those issues. It would be
better to have a way to control the FPU mode at inline-asm entry/exit somehow.
