// Test that the montavista gcc-toolchain is correctly detected

[Driver] Make -print-libgcc-file-name print compiler-rt lib when used Make the -print-libgcc-file-name option print an appropriate compiler runtime library, that is libgcc.a if gcc runtime is used and an appropriate compiler-rt library if that runtime is used. The main use for this is to allow linking executables built with -nodefaultlibs (e.g. to avoid linking to the standard C++ library) to the compiler runtime library, e.g. using: clang++ ... -nodefaultlibs $(clang++ ... -print-libgcc-file-name) in which case currently a program built like this linked to the gcc runtime unconditionally. The patch fixes it to use compiler-rt libraries instead when compiler-rt is the active runtime. Differential Revision: https://reviews.llvm.org/D25338 llvm-svn: 283746

Update two options to my proposed syntax for user-facing driver options: -gcc-toolchain foo -> --gcc-toolchain=foo -target foo -> --target=foo I've added legacy aliases for the original spellings. I've updated the canonical tests to check both spellings, and switched all of the -gcc-toolchain usages elsewhere in the test suite to use the new one. I've updated some of the usages of -target to the new syntax, but will finish that in a separate entirely mechanical change once I'm sure this won't get rolled back for some reason (It touches a *huge* number of RUN lines in the test suite unsurprisingly). A nice result is that the three most common flags I end up using when doing cross compiles are all now consistent: --target=, --sysroot=, and --gcc-toolchain=. llvm-svn: 184408
