13 daysall: add export linknames for assembly symbols accessed from other packageCherry Mui
For Go symbols accessed from other package via linkname or assembly, we have an export linkname from the definition side. We currently don't always have the linkname directive for assembly functions, for which external accesses are allowed. We may want to tighten up the restriction. So add export linknames for the ones that are needed.

Solaris The -lsocket and -lxnet flags are needed for accept4 syscall on Solaris. The runtime/cgo package doens't use them, so it doesn't make sense for it to explicitly link against those libraries. Instead, use the //go:cgo_ldflag in the syscall package.

So CL 45115 fixed windows syscall.Exit by calling runtime.exit. Austin suggested that all OSes should do the same, and this CL implements his idea. While making changes, I discovered that nacl syscall.Exit returned error func Exit(code int) (err error) and I changed it into func Exit(code int) like all other OSes. I assumed it was a mistake and it is OK to do because cmd/api does not complain about it. Also I changed plan9 runtime.exit to accept int32 just like all other OSes do.

2015-05-06runtime, syscall: link Solaris binaries directly instead of using dlopen/dlsymAram Hăvărneanu
Before CL 8214 (use .plt instead of .got on Solaris) Solaris used a dynamic linking scheme that didn't permit lazy binding. To speed program startup, Go binaries only used it for a small number of symbols required by the runtime. Other symbols were resolved on demand on first use, and were cached for subsequent use. This required some moderately complex code in the syscall package. CL 8214 changed the way dynamic linking is implemented, and now lazy binding is supported. As now all symbols are resolved lazily by the dynamic loader, there is no need for the complex code in the syscall package that did the same. This CL makes Go programs link directly with the necessary shared libraries and deletes the lazy-loading code implemented in Go.
