The CC and CXX environment variables now support spaces and quotes (both double and single). This fixes two issues: first, if CC is a single path that contains spaces (like 'c:\Program Files\gcc\bin\gcc.exe'), that should now work if the space is quoted or escaped (#41400). Second, if CC or CXX has multiple arguments (like 'gcc -O2'), they are now split correctly, and the arguments are passed before other arguments when invoking the C compiler. Previously, strings.Fields was used to split arguments, and the arguments were placed later in the command line. (#43078). Fixes golang/go#41400 Fixes golang/go#43078 NOTE: This change also includes a fix (CL 341929) for a test that was broken by the original CL. Commit message for the fix is below. [dev.cmdgo] cmd/link: fix TestBuildForTvOS This test was broken in CL 334732 on darwin. The test invokes 'go build' with a CC containing the arguments -framework CoreFoundation. Previously, the go command split CC on whitespace, and inserted the arguments after the command line when running CC directly. Those arguments weren't passed to cgo though, so cgo ran CC without -framework CoreFoundation (or any of the other flags). In CL 334732, we pass CC through to cgo, and cgo splits arguments using str.SplitQuotedFields. So -framework CoreFoundation actually gets passed to the C compiler. It appears that -framework flags are only meant to be used in linking operations, so when cgo invokes clang with -E (run preprocessor only), clang emits an error that -framework is unused. This change fixes the test by moving -framework CoreFoundation out of CC and into CGO_LDFLAGS.
