From a8ed047a5e068a88591f049c5d2b6ce33e7974cd Mon Sep 17 00:00:00 2001 From: RubenKelevra Date: Sat, 14 May 2022 00:39:39 +0200 Subject: [PATCH] Detect paths that trigger erroneous or undefined behavior docs: Detect paths that trigger erroneous or undefined behavior due to a null value being used in a way forbidden by a returns_nonnull or nonnull attribute. Isolate those paths from the main control flow and turn the statement with erroneous or undefined behavior into a trap. This is not currently enabled, but may be enabled by -O2 in the future. --- utils.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/utils.go b/utils.go index a2c2f6f..5b9d22a 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") + 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") 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+" \"")
