From 31de58baa7fab98041b7b6fc03384309b16ab0d7 Mon Sep 17 00:00:00 2001 From: RubenKelevra Date: Sat, 14 May 2022 21:34:46 +0200 Subject: [PATCH] assume loops are finite docs: Assume that a loop with an exit will eventually take the exit and not loop indefinitely. This allows the compiler to remove loops that otherwise have no side-effects, not considering eventual endless looping as such. This option is enabled by default at -O2 for C++ with -std=c++11 or higher. --- utils.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/utils.go b/utils.go index ad12456..74d2d95 100644 --- a/utils.go +++ b/utils.go @@ -727,7 +727,7 @@ func setupMakepkg(march string) error { } makepkgStr = strings.ReplaceAll(makepkgStr, " color ", " !color ") // Add align-functions=32, see https://github.com/InBetweenNames/gentooLTO/issues/164 for more - makepkgStr = strings.ReplaceAll(makepkgStr, "-O2", "-O3 -falign-functions=32 -mpclmul -fdevirtualize-at-ltrans -fgcse-sm -fgcse-las -flive-range-shrinkage -fira-loop-pressure -fsched-pressure -fmodulo-sched -fmodulo-sched-allow-regmoves -freschedule-modulo-scheduled-loops -fdelete-dead-exceptions -fgraphite -fgraphite-identity -fsplit-stack -fipa-pta -fisolate-erroneous-paths-attribute -fira-region=mixed -fsimd-cost-model=dynamic -frename-registers -fweb -ftree-vectorize -flto-partition=one") + makepkgStr = strings.ReplaceAll(makepkgStr, "-O2", "-O3 -falign-functions=32 -mpclmul -fdevirtualize-at-ltrans -fgcse-sm -fgcse-las -flive-range-shrinkage -fira-loop-pressure -fsched-pressure -fmodulo-sched -fmodulo-sched-allow-regmoves -freschedule-modulo-scheduled-loops -fdelete-dead-exceptions -fgraphite -fgraphite-identity -fsplit-stack -fipa-pta -fisolate-erroneous-paths-attribute -fira-region=mixed -fsimd-cost-model=dynamic -frename-registers -fweb -ftree-vectorize -flto-partition=one -ffinite-loops") makepkgStr = strings.ReplaceAll(makepkgStr, "#MAKEFLAGS=\"-j2\"", "MAKEFLAGS=\"-j"+strconv.Itoa(conf.Build.Makej)+"\"") makepkgStr = reMarch.ReplaceAllString(makepkgStr, "${1}"+march) makepkgStr = strings.ReplaceAll(makepkgStr, "#PACKAGER=\"John Doe \"", "PACKAGER=\"ALHP "+march+" \"")
