Computing the assembler name of a builtin function prevents the
middle-end from open coding the builtin. This was causing assembly
differences between the non-pph and pph compiles.
Tested on x86_64. Committed to branch.
Diego.
cp/ChangeLog.pph
* pph-streamer.c (pph_merge_name): Do not mangle names for
builtin functions.
testsuite/ChangeLog.pph
* g++.dg/pph/p2pr36533.cc: Mark fixed.
* g++.dg/pph/p4mean.cc: Likewise.
* g++.dg/pph/p4pr36533.cc: Likewise.
