Hello. Long time, no see.
After two years of active development, would like to introduce a new linker option for GCC’s -fuse-ld flag. This linker delivers significant performance improvements—achieving speeds comparable to the Mold linker—and has reached a mature stage, successfully linking large and complex projects such as Chromium and the Rust compiler (rustc). A few minor test-suite failures remain, primarily involving corner cases related to symbol versioning ([2]) and constructor/destructor ordering ([3]), and we are actively working to resolve them. Support for the GCC linker plug-in is not yet implemented. The linker currently supports x86_64, aarch64 and riscv64gc Linux platforms. The patch bootstraps with: --enable-languages=c++ --disable-lto --with-ld=`which wild` and vast majority of tests pass. Have a nice day, Martin [1] https://github.com/davidlattimore/wild [2] https://github.com/davidlattimore/wild/issues/1302 [3] https://github.com/davidlattimore/wild/issues/588 --- gcc/collect2.cc | 13 +++++-- gcc/common.opt | 4 ++ gcc/configure | 18 ++++++++- gcc/configure.ac | 82 +++++++++++++++++++++++---------------- gcc/doc/invoke.texi | 6 ++- gcc/gcc.cc | 5 +++ gcc/opts.cc | 1 + libatomic/acinclude.m4 | 6 +++ libatomic/configure | 5 +++ libgomp/acinclude.m4 | 6 +++ libgomp/configure | 5 +++ libitm/acinclude.m4 | 6 +++ libitm/configure | 5 +++ libstdc++-v3/acinclude.m4 | 8 +++- libstdc++-v3/configure | 49 ++++++++++++++++++----- 15 files changed, 168 insertions(+), 51 deletions(-) diff --git a/gcc/collect2.cc b/gcc/collect2.cc index 268ac378b9c..e84dc1cd437 100644 --- a/gcc/collect2.cc +++ b/gcc/collect2.cc @@ -777,6 +777,7 @@ main (int argc, char **argv) USE_BFD_LD, USE_LLD_LD, USE_MOLD_LD, + USE_WILD_LD, USE_LD_MAX } selected_linker = USE_DEFAULT_LD; static const char *const ld_suffixes[USE_LD_MAX] = @@ -786,7 +787,8 @@ main (int argc, char **argv) "ld.gold", "ld.bfd", "ld.lld", - "ld.mold" + "ld.mold", + "wild" }; static const char *const real_ld_suffix = "real-ld"; static const char *const collect_ld_suffix = "collect-ld"; @@ -868,7 +870,7 @@ main (int argc, char **argv) #ifdef CROSS_DIRECTORY_STRUCTURE /* lld and mold are platform-agnostic and not prefixed with target triple. */ - if (!(i == USE_LLD_LD || i == USE_MOLD_LD)) + if (!(i == USE_LLD_LD || i == USE_MOLD_LD || i == USE_WILD_LD)) full_ld_suffixes[i] = concat (target_machine, "-", ld_suffixes[i], NULL); else @@ -964,6 +966,8 @@ main (int argc, char **argv) selected_linker = USE_LLD_LD; else if (strcmp (argv[i], "-fuse-ld=mold") == 0) selected_linker = USE_MOLD_LD; + else if (strcmp (argv[i], "-fuse-ld=wild") == 0) + selected_linker = USE_WILD_LD; else if (startswith (argv[i], "-o")) { /* Parse the output filename if it's given so that we can make @@ -1056,7 +1060,8 @@ main (int argc, char **argv) ld_file_name = 0; #ifdef DEFAULT_LINKER if (selected_linker == USE_BFD_LD || selected_linker == USE_GOLD_LD || - selected_linker == USE_LLD_LD || selected_linker == USE_MOLD_LD) + selected_linker == USE_LLD_LD || selected_linker == USE_MOLD_LD || + selected_linker == USE_WILD_LD) { char *linker_name; # ifdef HOST_EXECUTABLE_SUFFIX @@ -1293,7 +1298,7 @@ main (int argc, char **argv) else if (!use_collect_ld && startswith (arg, "-fuse-ld=")) { - /* Do not pass -fuse-ld={bfd|gold|lld|mold} to the linker. */ + /* Do not pass -fuse-ld={bfd|gold|lld|mold|wild} to the linker. */ ld1--; ld2--; } diff --git a/gcc/common.opt b/gcc/common.opt index 9bc0c65c457..d44f713ae34 100644 --- a/gcc/common.opt +++ b/gcc/common.opt @@ -3448,6 +3448,10 @@ fuse-ld=mold Common Driver Negative(fuse-ld=mold) Use the Modern linker (MOLD) linker instead of the default linker. +fuse-ld=wild +Common Driver Negative(fuse-ld=wild) +Use the Wild linker instead of the default linker. + fuse-linker-plugin Common Undocumented Var(flag_use_linker_plugin) diff --git a/gcc/configure b/gcc/configure index 0e8a63c34fa..4bd5e75d83c 100755 --- a/gcc/configure +++ b/gcc/configure @@ -25562,6 +25562,18 @@ fi { $as_echo "$as_me:${as_lineno-$LINENO}: result: $ld_is_mold" >&5 $as_echo "$ld_is_mold" >&6; } +# Check to see if we are using Wild instead of ld +{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether we are using wild" >&5 +$as_echo_n "checking whether we are using wild...
