Ian Lance Taylor 754f707f5f cmd/link, cmd/go, cmd/dist: use copy of libgcc.a for internal linking ... 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. Change-Id: I1ab28182263238d9bcaf6a42804e5da2a87d8778 Reviewed-on: https://go-review.googlesource.com/16741 Reviewed-by: Russ Cox <rsc@golang.org>		2015-11-14 18:56:17 +00:00
