Revert r352985 "[X86] Print %st(0) as %st to match what gcc inline asm uses as the clobber name to make MS inline asm work correctly" Looking into gcc and objdump behavior more this was overly aggressive. If the register is encoded in the instruction we should print %st(0), if its implicit we should print %st. I'll be making a more directed change in a future patch. llvm-svn: 353013

[X86] Print all register forms of x87 fadd/fsub/fdiv/fmul as having two arguments where on is %st. All of these instructions consume one encoded register and the other register is %st. They either write the result to %st or the encoded register. Previously we printed both arguments when the encoded register was written. And we printed one argument when the result was written to %st. For the stack popping forms the encoded register is always the destination and we didn't print both operands. This was inconsistent with gcc and objdump and just makes the output assembly code harder to read. This patch changes things to always print both operands making us consistent with gcc and objdump. The parser should still be able to handle the single register forms just as it did before. This also matches the GNU assembler behavior. llvm-svn: 353061

[X86] Describe wbnoinvd instruction Similar to the wbinvd instruction, except this one does not invalidate caches. Ring 0 only. The encoding matches a wbinvd instruction with an F3 prefix.

[X86] WaitPKG instructions Three new instructions: umonitor - Sets up a linear address range to be monitored by hardware and activates the monitor. The address range should be a writeback memory caching type. umwait - A hint that allows the processor to stop instruction execution and enter an implementation-dependent optimized state until occurrence of a class of events. tpause - Directs the processor to enter an implementation-dependent optimized state until the TSC reaches the value in EDX:EAX. Also modifying the description of the mfence instruction, as the rep prefix (0xF3) was allowed before, which would conflict with umonitor during disassembly. Before: $ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble .text mfence After: $ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble .text umonitor %rax Reviewers: craig.topper, zvi Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D45253 llvm-svn: 330462
