Reapply "Add support for #pragma float_control" with buildbot fixes Add support for #pragma float_control Reviewers: rjmccall, erichkeane, sepavloff Differential Revision: https://reviews.llvm.org/D72841 This reverts commit fce82c0ed310174fe48e2402ac731b6340098389. 2020-05-02 01:32:06 +08:00			`// RUN: %clang_cc1 -ffast-math -ffp-contract=fast -emit-llvm -o - %s \| FileCheck %s`
Remove unneeded typedef and volatile llvm-svn: 169743 2012-12-11 02:48:08 +08:00			`float f0, f1, f2;`
Have clang use LLVM IR's fast-math flags when in FastMath or FiniteMathOnly modes. Test cases included. llvm-svn: 169191 2012-12-04 08:36:06 +08:00
			`void foo(void) {`
Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971 2015-06-30 01:29:50 +08:00			`// CHECK-LABEL: define {{.*}}void @foo()`
