* [PragmaHandler] Expose `#pragma` locationJoel E. Denny2019-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Currently, a pragma AST node's recorded location starts at the namespace token (such as `omp` in the case of OpenMP) after the `#pragma` token, and the `#pragma` location isn't available. However, the `#pragma` location can be useful when, for example, rewriting a directive using Clang's Rewrite facility. This patch makes `#pragma` locations available in any `PragmaHandler` but it doesn't yet make use of them. This patch also uses the new `struct PragmaIntroducer` to simplify `Preprocessor::HandlePragmaDirective`. It doesn't do the same for `PPCallbacks::PragmaDirective` because that changes the API documented in `clang-tools-extra/docs/pp-trace.rst`, and I'm not sure about backward compatibility guarantees there.

| | | | | | | | | | | | | | | | | | | | | | | (SHF_COMPRESSED) Since July 15, 2015 (binutils-gdb commit 19a7fe52ae3d0971e67a134bcb1648899e21ae1c, included in 2.26), gas --compress-debug-sections=zlib (gcc -gz) means zlib-gabi: SHF_COMPRESSED. Before that it meant zlib-gnu (.zdebug). clang's -gz was introduced in rC306115 (Jun 2017) to indicate zlib-gnu. It is 2019 now and it is not unreasonable to assume users of the new feature to have new linkers (ld.bfd/gold >= 2.26, lld >= rLLD273661). Change clang's default accordingly to improve standard conformance. zlib-gnu becomes out of fashion and gets poorer toolchain support. Its mangled names confuse tools and are more likely to cause problems.

* [PowerPC] Add the support for __builtin_setrnd() in clangKang Zhang2019-03-291-0/+72
| | | | | | | | | | | | | | | | | | | | Summary: PowerPC64/PowerPC64le supports the builtin function __builtin_setrnd to set the floating point rounding mode. This function will use the least significant two bits of integer argument to set the floating point rounding mode. double __builtin_setrnd(int mode); The effective values for mode are: 0 - round to nearest 1 - round to zero 2 - round to +infinity 3 - round to -infinity Note that the mode argument will modulo 4, so if the int argument is greater than 3, it will only use the least significant two bits of the mode. Namely, builtin_setrnd(102)) is equal to builtin_setrnd(2).
