Move unit tests to target specific directories. Differential Revision: http://reviews.llvm.org/D10522 llvm-svn: 243454

X86: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774

[TLS] use emulated TLS if the target supports only this mode Emulated TLS is enabled by llc flag -emulated-tls, which is passed by clang driver. When llc is called explicitly or from other drivers like LTO, missing -emulated-tls flag would generate wrong TLS code for targets that supports only this mode. Now use useEmulatedTLS() instead of Options.EmulatedTLS to decide whether emulated TLS code should be generated. Unit tests are modified to run with and without the -emulated-tls flag.

[TLS] New lower emutls pass, fix linkage bugs. Previous implementation in http://reviews.llvm.org/D10522 created external references to __emutls_v.* variables. Such references are inaccurate and cannot be handled by all linkers, e.g. Android dynamic and gold linkers for aarch64. Now a new LowerEmuTLS pass to go through all global variables, and add emutls_v.* and emutls_t.* variables. These __emutls* variables have the same linkage and visibility as the associated user defined TLS variable. Also removed old code that dump __emutls* variables in AsmPrinter.cpp, and updated TLS unit tests. Differential Revision: http://reviews.llvm.org/D15300 llvm-svn: 257718

[MC] Use .p2align instead of .align For historic reasons, the behavior of .align differs between targets. Fortunately, there are alternatives, .p2align and .balign, which make the interpretation of the parameter explicit, and which behave consistently across targets. This patch teaches MC to use .p2align instead of .align, so that people reading code for multiple architectures don't have to remember which way each platform does its .align directive.
