From fea61b9e1973a6ca7efe6cdf91e87c7604d54dd6 Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Thu, 23 May 2024 23:40:10 -0500 Subject: system/gcc: Update to 13.3.0 0012-static-pie and 201-ada were forward-ported by my own paws. Three digit 0xx underscore patches are from Gentoo. This is also the source of the insn-split and match-split patches, which significantly increase performance on build. They are also the source of the new configure option --with-matchpd-partitions. On systems with very many cores/threads, a number higher than 32 would probably perform even better, but 32 should give decent perf on 8+ threads, and runs quite nicely on the 64-thread Talos II I ran the testbuild on. 202 is from Void. The 300s are originally written by me. The Ada patch now includes an improvement to use posix_openpt instead of getpt, which fixes link errors later on. We also now use STAGE1_CFLAGS and BOOT_CFLAGS to improve build times. Improvement was clocked from 40m to 32m (-8m, or 20%) on gwyn. The patch for Go name mangling is needed to build packages that use reflect2, which includes user/gitlab-runner. --- system/gcc/336-gccgo-mmap64.patch | 17 ++++------------- 1 file changed, 4 insertions(+), 13 deletions(-) (limited to 'system/gcc/336-gccgo-mmap64.patch') diff --git a/system/gcc/336-gccgo-mmap64.patch b/system/gcc/336-gccgo-mmap64.patch index 23b4cebc8..0d4ab19b8 100644 --- a/system/gcc/336-gccgo-mmap64.patch +++ b/system/gcc/336-gccgo-mmap64.patch @@ -1,15 +1,15 @@ --- gcc-8.3.0/libgo/go/runtime/mem_gccgo.go.old 2018-01-09 01:23:08.000000000 +0000 +++ gcc-8.3.0/libgo/go/runtime/mem_gccgo.go 2019-03-03 05:15:33.010000000 +0000 -@@ -16,7 +16,7 @@ - //go:linkname sysFree runtime.sysFree +@@ -15,7 +15,7 @@ + //go:linkname sysFree - //extern mmap + //extern __go_mmap -func sysMmap(addr unsafe.Pointer, n uintptr, prot, flags, fd int32, off uintptr) unsafe.Pointer +func sysMmap(addr unsafe.Pointer, n uintptr, prot, flags, fd int32, off int64) unsafe.Pointer //extern munmap func munmap(addr unsafe.Pointer, length uintptr) int32 -@@ -41,7 +41,7 @@ +@@ -37,7 +37,7 @@ } } @@ -18,12 +18,3 @@ p := sysMmap(addr, n, prot, flags, fd, off) if uintptr(p) == _MAP_FAILED { return nil, errno() -@@ -84,7 +84,7 @@ - return true - } - --func mmap_fixed(v unsafe.Pointer, n uintptr, prot, flags, fd int32, offset uintptr) (unsafe.Pointer, int) { -+func mmap_fixed(v unsafe.Pointer, n uintptr, prot, flags, fd int32, offset int64) (unsafe.Pointer, int) { - p, err := mmap(v, n, prot, flags, fd, offset) - // On some systems, mmap ignores v without - // MAP_FIXED, so retry if the address space is free. -- cgit v1.2.3-70-g09d2
