Bug ID: 111828
Summary: rs6000: Parse inline asm string to figure out it
requires HTM feature or not.
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: linkw at gcc dot gnu.org
CC: jan.wassenberg at gmail dot com, john_platts at hotmail dot

Depends on: 111366
Target Milestone: ---
Target: powerpc64le
Currently as the discussion in PR111366 we simply make the assumption that all
inline asm strings are possible to adopt HTM feature and consider it as
possible as conservative so that set HTM flag.
Technically speaking we are able to parse the inline asm string and figure out
it's HTM related or not. Excepting for the HTM specific instructions like
.tbegin etc., we also need to take care of those special registers related to
HTM feature.
