2013-06-21compiler: do not skip compilation of blank-named functions.Ian Lance Taylor3-3/+22
Fixes issue 22. From-SVN: r200316
2013-06-21Fix HLE example in manualAndi Kleen2-2/+9
The HLE example in the manual only commits when using bool for the flag, because __atomic_clear only writes bool, and HLE requires the acquire and release to match. So when the example is copied with e.g. an int variable it does not commit and causes slower than expected performance. Some people are running into problems because of this. Switch it over to use __atomic_store. Also fix a minor typo nearby. gcc/: 2013-06-21 Andi Kleen <ak@linux.intel.com> * doc/extend.texi: Dont use __atomic_clear in HLE example. Fix typo.

2013-06-18compiler, runtime: Use function descriptors.Ian Lance Taylor13-292/+957
This changes the representation of a Go value of function type from being a pointer to function code (like a C function pointer) to being a pointer to a struct. The first field of the struct points to the function code. The remaining fields, if any, are the addresses of variables referenced in enclosing functions. For each call to a function, the address of the function descriptor is passed as the last argument. This lets us avoid generating trampolines, and removes the use of writable/executable sections of the heap. From-SVN: r200181
