runtime: use new #include "textflag.h" I did this just to clean things up, but it will be important when we drop the pkg directory later. LGTM=bradfitz R=r, bradfitz CC=golang-codereviews https://golang.org/cl/132600043 2014-09-04 21:05:18 -06:00			`#include "textflag.h"`

runtime, sync/atomic: use NOFRAME on arm This replaces frame size -4 with the NOFRAME flag in arm assembly. This was automated with: sed -i -e 's/\(^TEXT.[A-Z]\),\( \)\$-4/\1\|NOFRAME,\2$0/' $(find -name '_arm.s') Plus three manual comment changes found by: grep '\$-4' $(find -name '_arm.s') The go binary is identical before and after this change.

runtime: convert a few traceback-related functions from proc.c to traceback.go They were in proc.c mainly because there was no portable traceback source file. As part of converting them to Go, move to traceback.go. In order to get access to the PC of _rt0_go, rename to runtime.rt0_go.
