Bug ID: 122951
Summary: flatten_depth attribute should be added
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Currently GCC has a flatten attribute which is infinite flatten (LLVM
[incorrectly?] implemented it as just one level which is why GCC has a compile
time issue with it) but it would be nice to have an attribute which limits the
depth of the flatten due to compile time (especially with respect to LTO).
See
https://discourse.llvm.org/t/rfc-function-level-flatten-depth-attribute-for-depth-limited-inlining/89017/
also.
