2016-10-10compiler: prune away gcc-specific linemap usageThan McIntosh5-2/+28
Add an interface to the go Linemap class to allow clients to ask for the line number for a Location (for debugging dumps), so as to move some gcc-specific location code into the back end. Reviewed-on: https://go-review.googlesource.com/30699 * go-linemap.cc (Gcc_linemap::location_line): New method. From-SVN: r240942
2016-10-10runtime: copy channel code from Go 1.7 runtimeIan Lance Taylor7-57/+118
Change the compiler to use the new routines. Drop the separation of small and large values when sending on a channel. Allocate the select struct on the stack. Remove the old C implementation of channels. Adjust the garbage collector for the new data structure. Bring in part of the tracing code, enough for the channel code to call. Bump the permitted number of allocations in one of the tests in context_test.go. The difference is that now receiving from a channel allocates a sudog, which the C code used to simply put on the stack. This will be somewhat better when we port proc.go.

2016-10-10S/390: Wrap more macro args into ()Andreas Krebbel2-43/+49
Turned out that there where a few () around macro args uses missing. One real problem with it was detected with the int-in-bool-context in the definition of DBX_REGISTER_NUMBER. But while being at it I've also tried to fix other places where brackets might be missing. gcc/ChangeLog: 2016-10-10 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/s390.h: Wrap more macros args in brackets and fix some formatting.
