Partial revert of r185568. r186899 and r187061 added a preferred way for some architectures not to get intrinsic generation for math builtins. So the code changes in r185568 can now be undone (the test remains). llvm-svn: 187079

// RUN: %clang_cc1 -fno-math-builtin -fmath-errno -emit-llvm -o - %s -triple le32-unknown-nacl | FileCheck %s
// RUN: %clang_cc1 -fno-math-builtin -emit-llvm -o - %s -triple le32-unknown-nacl | FileCheck %s
Add target hook CodeGen queries when generating builtin pow*. Without fmath-errno, Clang currently generates calls to @llvm.pow.* intrinsics when it sees pow*(). This may not be suitable for all targets (for example le32/PNaCl), so the attached patch adds a target hook that CodeGen queries. The target can state its preference for having or not having the intrinsic generated. Non-PNaCl behavior remains unchanged; PNaCl-specific test added. llvm-svn: 185568

// le32 (PNaCl) never generates intrinsics for pow calls, with or without
// errno, when the -fno-math-builtin flag is passed to -cc1. A separate test
// makes sure this flag is indeed passed for le32.

Revert "[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition" This reverts commit 789a46f2d742e11edaade28cb59a0f4d2a1d770e. Accidentally committed.
