testsuite: armv7l test failure

I noticed the following test failure on the target: ``` [ 181s] + /usr/bin/make -O -j4 V=1 VERBOSE=1 test -e PREFIX=/usr BINDIR=/usr/bin MANDIR=/usr/share/man LIBDIR=/usr/lib LIBEXECDIR=/usr/libexec STRIP=true SYSTEM_TBB=1 SYSTEM_XXHASH=1 SYSTEM_MIMALLOC=1 [...

Consider doing bootstrap (PGO bootstrap)

21

Similar to GCC, `mold` can easily bootstrap (link `mold` using already built `mold`). Plus you can squeeze some extra performance from PGO (`-fprofile-generate` and `-fprofile-use`), where linking of `mold` can...

Partial linking (-r) with LTO

I noticed that LTO is not run for partial linking: ``` $ cat partial.C class Container { public: virtual ~Container (); }; class List : public Container { }; static...

Support LTO linker plugin

76

Similarly to #93, please consider adding `-flto` support for GCC bytecode. Your linker looks very promising and LTO is getting more commonly used. Note there are distros like openSUSE, Fedora,...

Is s390x supported?

I noticed one can't build `mold` on `s390x` due to: ``` [ 33s] make[3]: Entering directory '/home/abuild/rpmbuild/BUILD/mold-1.0.999+git.20220109.b18d4881/out/mimalloc' [ 33s] [100%] Built target mimalloc-static [ 33s] make[3]: Leaving directory '/home/abuild/rpmbuild/BUILD/mold-1.0.999+git.20220109.b18d4881/out/mimalloc' [...

Support GCOV intermediate format

For GCC 9.1 I'm planning to come up with JSON format of the intermediate representation. It's feasible for consumers of the information like lcov and gcovr Feel free to comment...
