Bug ID: 58105
Summary: wrong code generation for multiversioned functions
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bernd.edlinger at hotmail dot de
the following test cases fail on i686-*:
g++.dg/ext/mv2.C
g++.dg/ext/mv5.C
g++.dg/ext/mv12.C
The code is OK on -O0, -O1, but fails on -O2 and -O3.
The problem seems to be that for multiversioned functions
an internal dispatcher function is generated by
ix86_generate_version_dispatcher_body(), which is being inlined in -O2
and above.
But the inlined function does no longer call the target-specific function.
Instead the return value is the address of the target-specific function.
