The gcc name mangling for gnu multiversions includes a _Znum_ prefix
e.g. the test case in the gcc testsuite named mv1.C
.quad _Z13_Z3foov.ifuncv
call _Z13_Z3foov.ifuncv
.globl _Z13_Z3foov.ifuncv
.type _Z13_Z3foov.ifuncv, @gnu_indirect_function
.set _Z13_Z3foov.ifuncv,_Z3foov.resolver
Is the _Z13 prefix needed? It seems like the .ifunc suffix would be adequate.
grep ifunc *.s | grep call
mv12.s: call _Z13_Z3foov.ifuncv
mv12.s: call _Z13_Z3foov.ifuncv
mv1.s: call _Z13_Z3foov.ifuncv
mv2.s: call _Z13_Z3foov.ifuncv
mv5.s: call _Z13_Z3foov.ifuncv
mv6.s: call _Z19_ZN3Foo3fooEv.ifuncP3Foo
Do you expect the name mangling will be added to a standards document?
Thanks and regards
