[mips][mips64r6] Improve tests affected by the changes to multiplies and divides Summary: MIPS32r6/MIPS64r6 support has not been added yet. inlineasm-cnstrnt-reg.ll: Explicitly specify the CPU since it will not work on MIPS32r6/MIPS64r6 when -integrated-as is the default. We can't change the mnemonic since the LO register is an implicit def of mtlo and MIPS32r6/MIPS64r6 has no instructions that use LO. 2008-08-01-AsmInline.ll: Explicitly specify the CPU since MIPS32r6/MIPS64r6 will correctly emit different code and this is a regression test. mips64instrs.ll and mips64muldiv.ll Check registers and the way the multiply is used in m1 divrem.ll Check registers and use multiple filecheck prefixes to limit redundancy Reviewers: vmedic, jkolek, zoran.jovanovic, matheusalmeida Reviewed By: matheusalmeida Subscribers: matheusalmeida Differential Revision: http://reviews.llvm.org/D3894 llvm-svn: 210656

[mips] Set GCC-compatible MIPS asssembler options before inline asm blocks. Summary: When generating MIPS assembly, LLVM always overrides the default assembler options by emitting the '.set noreorder', '.set nomacro' and '.set noat' directives, while GCC uses the default options if an assembly-level function contains inline assembly code. This becomes a problem when the code generated by LLVM is interleaved with inline assembly which assumes GCC-like assembler options (from Linux, for example). This patch fixes these conflicts by setting the appropriate assembler options at the beginning of an inline asm block and popping them at the end.
