LLVM's code generator does not currently support split stacks for vararg functions, so we disable split stacks for the only function that uses this feature under Clang. This appears to be OK as long as: - this function only calls non-inlined, internal-linkage (hence no dynamic loader) functions compiled with split stacks (i.e. go_vprintf), which can allocate more stack space as required; - this function itself does not occupy more than BACKOFF bytes of stack space (see libgcc/config/i386/morestack.S). These conditions are currently known to be satisfied by Clang on x86-32 and x86-64. Note that signal handlers receive slightly less stack space than they would normally do if they happen to be called while this function is being run. If this turns out to be a problem we could consider increasing BACKOFF. From-SVN: r211037 |

See ../README. This is the runtime support library for the Go programming language. This library is intended for use with the Go frontend. The library has only been tested on GNU/Linux using glibc. It should not be difficult to port to other operating systems. The library has only been tested on x86/x86_64 systems. It should not be difficult to port to other architectures. Directories: go A copy of the Go library from http://golang.org/, with a few changes for gccgo. Notably, the reflection interface is different. runtime Runtime functions, written in C, which are called directly by the compiler or by the library. syscalls System call support.
