Update comment about is_leaf
crtl->is_leaf has a comment above it referring to "Local Register
Allocation". However this is set by IRA and not LRA since the meaning
of Local Register Allocator in GCC has changed quite drastically since
1999 when this comment was introduced above the variable
current_function_is_leaf. From memory gcc in those days had "local"
and "global" register allocation - however all of this has changed
quite a bit drastically since.
This patch merely updates the comment as I did some head scratching
this morning about how this could be set before Local Register
Allocator especially given the comment in ira.c as below.
/* Determine if the current function is a leaf before running IRA
since this can impact optimizations done by the prologue and
epilogue thus changing register elimination offsets. */
crtl->is_leaf = leaf_function_p ();

Recognize '-' as special -MF argument (write to stdout)
Sometimes it is useful to generate pre-processed output to a file and
the dependency information to stdout for further analysis/processing.
For example:
g++ -E -MD -fdirectives-only -o test.ii test.cxx
This will generate the dependency information to test.d (as per the
documentation). While changing this behavior is probably unwise, one
traditional (e.g., supported by -o) way to handle this is to recognize
the special '-' file name as an instruction to write to stdout:
g++ -E -MD -fdirectives-only -o test.ii -MF - test.cxx
Currently this will create a file named '-'. The included patch
changes this behavior to write to stdout.

The go tool will pass -I objdir as one of the flags, where objdir is
the temporary build directory. Remove that from _cgo_flags: we don't

Sort the flags to avoid the unpredictable map iteration order.
This matters for gccgo because for a package that uses cgo, the go
tool when building for gccgo will store the _cgo_flags file in the

runtime: ignore _Gscan bit when checking status in CgocallDone
Also always access the atomicstatus field atomically.
The effect of not checking the _Gscan bit is that if the GC decides to
scan the stack just as the goroutine is leaving the system call, the
goroutine might fail to call exitsyscall. Then then typically causes
a runtime assertion failure later on. If we do call exitsyscall as we
should, it will stall (in casgstatus) until the _Gscan bit is cleared.
No separate test. I've observed causing sporadic failures running the
misc/cgo tests, but we don't currently have a way to run those
routinely for gccgo. I should fix that.
