      encoding/json: use reflect.SetBytes when decoding bytes · c60707b1
      Håvard Haugen authored 
      This allows slices of custom types with byte as underlying type to be
decoded, fixing a regression introduced in CL 9371.

Fixes #12921.

      cmd/link, cmd/go, cmd/dist: use copy of libgcc.a for internal linking · 754f707f
      Ian Lance Taylor authored 
      Change the linker to use a copy of the C compiler support library,
libgcc.a, when doing internal linking.  This will be used to satisfy any
undefined symbols referenced by host objects.

Change the dist tool to copy the support library into a new directory
tree under GOROOT/pkg/libgcc.  This ensures that libgcc is available
even when building Go programs on a system that has no C compiler.  The
C compiler is required when building the Go installation in the first
place, but is not required thereafter.

Change the go tool to not link libgcc into cgo objects.

Correct the linker handling of a weak symbol in an ELF input object to
not always create a new symbol, but to use an existing symbol if there
is one; this is necessary on freebsd-amd64, where libgcc contains a weak
definition of compilerrt_abort_impl.

Fixes #9510.
