      cmd/cgo: stop using -fno-eliminate-unused-debug-types · adda3348
      Russ Cox authored 
      This flag was added in January 2010, in CL 181102, to fix issue 497.
(Numbers were just shorter back then.) The fix was for OS X machines
and the llvm-gcc frontend.

In July 2011 we had to change the way we get enum values, because
there were no flags available to force Xcode's llvm-gcc to include the
enum names and values in DWARF debug output.

We now use clang, not llvm-gcc, on OS X machines.
Earlier versions of clang printed a warning about not knowing the flag.
Newer versions of clang now make that an error.

That is:
 - The flag was added for OS X machines.
 - The flag is no longer necessary on OS X machines.
 - The flag now breaks some OS X machines.

Remove it.

I have run the original program from issue 497 successfully
without the flag on both OS X and Linux machines.

Fixes #6678.

      cmd/cgo: stop using compiler error message text to analyze C names · 06ad3b2d
      Russ Cox authored 
      The old approach to determining whether "name" was a type, constant,
or expression was to compile the C program

        name;

and scan the errors and warnings generated by the compiler.
This requires looking for specific substrings in the errors and warnings,
which ties the implementation to specific compiler versions.
As compilers change their errors or drop warnings, cgo breaks.
This happens slowly but it does happen.
Clang in particular (now required on OS X) has a significant churn rate.

The new approach compiles a slightly more complex program
that is either valid C or not valid C depending on what kind of
thing "name" is. It uses only the presence or absence of an error
message on a particular line, not the error text itself. The program is:

        // error if and only if name is undeclared
        void f1(void) { typeof(name) *x; }

        // error if and only if name is not a type
        void f2(void) { name *x; }

        // error if and only if name is not an integer constant
        void f3(void) { enum { x = (name)*1 }; }

I had not been planning to do this until Go 1.3, because it is a
non-trivial change, but it fixes a real Xcode 5 problem in Go 1.2,
and the new code is easier to understand than the old code.
It should be significantly more robust.

Fixes #6596.
Fixes #6612.

      cmd/gc: shorten name used for map bucket type · 20f99ffa
      Russ Cox authored 
      Before:
type.struct { buckets *struct { overflow *struct { overflow *struct { overflow *struct { overflow *struct { overflow *<...>; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; oldbuckets *struct { overflow *struct { overflow *struct { overflow *struct { overflow *struct { overflow *<...>; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable }; keys [8]string; values [8]*"".RangeTable } }

After:
type.map.bucket[string]*"".RangeTable

This makes debugging maps a little nicer, and it takes up less space in the binary.

      runtime: remove nomemprof · f6329700
      Dmitriy Vyukov authored 
      Nomemprof seems to be unneeded now, there is no recursion.
If the recursion will be re-introduced, it will break loudly by deadlocking.
