* Preprocessor: improve ACLE 6.4.1, 6.4.2 supportSaleem Abdulrasool2014-06-15
| | | | | | | | | | | | | | | | | | This improves conformance with ACLE 6.4.1. Define additional macros that indicate support for the ARM and Thumb instruction set architecture. This includes the following set of macros: __ARM_ARCH __ARM_ARCH_ISA_ARM __ARM_ARCH_ISA_THUMB __ARM_32BIT_STATE These help identify the environment that the code is intended to execute on. Adjust the handling for ACLE 6.4.2 to be more correct. We would define the profile as a free-standing token rather than a quoted single character. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210991 91177308-0d34-0410-b5e6-96231b3b80d8
* [AArch64] Add default features for CPUs on AArch64 target.Kevin Qin2014-06-11
| | | | | | | | | | For ARM target, we can use CRYPTO and CRC features if we select cortex-a57 by '-mcpu', but for AArch64 target, it doesn't work unless adding with '-mfpu=crypto-neon-fp-armv8'. To keep consistency between front-end and back-end and get end-users more easier to use, we'd better add default feature for CPUs on AArch64 target as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210625 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | contents than the header file by the same name under the system header search root. Surprisingly, this is required to get the test to pass on some systems. So, it turns out that there exist filesystems in the world which unique the inode of all files based on their contents. This results in two files with the same contents at different paths suddenly having the same inode. This doesn't actually cause any problems in practice as the contents are the same, and the path used to access the files are the same. However, it can cause tests like this one to be more brittle because the file manager ends up de-duplicating the file entries by inode. We don't have any other really easy ways to observe the behavior shift because the whole point is that the #include written in the source code doesn't contain the information -- instead it is contained in the header map. If folks have other solutions they would prefer, I'm more than happy to work on them, but this seems a reasonable way to ensure that the test in question exercises the code it wants to exercise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@205149 91177308-0d34-0410-b5e6-96231b3b80d8
