X-Git-Tag: releases/gcc-12.5.0~562
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=42d4aa02c6016cc8efd896f627f692896e68c914;p=thirdparty%2Fgcc.git

ipa: Don't disable function parameter analysis for fat LTO

Update analyze_parms not to disable function parameter analysis for
-ffat-lto-objects.  Tested on x86-64, there are no differences in zstd
with "-O2 -flto=auto" -g "vs -O2 -flto=auto -g -ffat-lto-objects".

	PR ipa/116410
	* ipa-modref.cc (analyze_parms): Always analyze function parameter
	for LTO.
