Pull clang-cc code for generating PTH files based on the input type. - <rdar://problem/6741594> [pth] don't abuse -x to drive pth generation - Simpler, and fixes PR3915. Cleanup test cases for PTH: - Update to use -emit-pth - Removed PTH test of carbon.c and cocoa.mm; these didn't actually verify anything, and since PTH is token based the extra coverage (over cocoa.m) isn't particularly helpful. - Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase available parallelism when running tests. Ted, could you update the PTH test cases (include-pth.c and cocoa-pth.m) to have some sort of positive check that the PTH is getting used? "# of PTH cache hits" or "tokens read from PTH cache" statistics would work great. :) llvm-svn: 68189 2009-04-01 13:09:09 +08:00			`// RUN: clang-cc -emit-pth %s -o %t &&`
Rename clang to clang-cc. Tests and drivers updated, still need to shuffle dirs. llvm-svn: 67602 2009-03-24 10:24:46 +08:00			`// RUN: clang-cc -include-pth %t %s -E \| grep 'file_to_include' \| count 2`
Fix include-pth.c test case to (hopefully) more resilient to where and how tests are executed. llvm-svn: 67419 2009-03-21 07:45:36 +08:00			`#include "file_to_include.h"`
