From c8d28055ec71c585cdf5d9b6efd7cf96f3e9abad Mon Sep 17 00:00:00 2001 From: RubenKelevra Date: Sat, 14 May 2022 21:03:06 +0200 Subject: [PATCH] Constructs webs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit docs: Constructs webs as commonly used for register allocation purposes and assign each web individual pseudo register. This allows the register allocation pass to operate on pseudos directly, but also strengthens several other optimization passes, such as CSE, loop optimizer and trivial dead code remover. It can, however, make debugging impossible, since variables no longer stay in a “home register”. --- utils.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/utils.go b/utils.go index 32edc5b..5948d87 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") + 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") 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+" \"")
