ARM: fix `-mlong-calls` for WoA Not all code-paths set the relocation model to static for Windows. This currently breaks on Windows ARM with `-mlong-calls` when built with clang. Loosen the assertion to what it was previously. We would ideally ensure that all the configuration sets Windows to static relocation model. llvm-svn: 274570

ARM: correct assertion for long-calls on WoA COFF/PE, so the relocation model is never static. Loosen the assertion accordingly. The relocation can still be emitted properly, as it will be converted to an IMAGE_REL_ARM_ADDR32 which will be resolved by the loader taking the base relocation into account. This is necessary to permit the emission of long calls which can be controlled via the -mlong-calls option in the driver. llvm-svn: 210399

Correct PrivateLinkage for COFF - Use storage class C_STAT for 'PrivateLinkage' The storage class for PrivateLinkage should equal to the Internal Linkage. - Set 'PrivateGlobalPrefix' from "L" to ".L" for MM_WinCOFF (includes x86_64) MM_WinCOFF has empty GlobalPrefix '\0' so PrivateGlobalPrefix "L" may conflict to the normal symbol name starting with 'L'. Based on a patch by Han Sangjin! Manually updated test cases. llvm-svn: 284096

[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.
