MIR Serialization: Change MIR syntax - use custom syntax for MBBs. This commit modifies the way the machine basic blocks are serialized - now the machine basic blocks are serialized using a custom syntax instead of relying on YAML primitives. Instead of using YAML mappings to represent the individual machine basic blocks in a machine function's body, the new syntax uses a single YAML block scalar which contains all of the machine basic blocks and instructions for that function. This is an example of a function's body that uses the old syntax: body: - id: 0 name: entry instructions: - '%eax = MOV32r0 implicit-def %eflags' - 'RETQ %eax' ... The same body is now written like this: body: | bb.0.entry: %eax = MOV32r0 implicit-def %eflags RETQ %eax ... This syntax change is motivated by the fact that the bundled machine instructions didn't map that well to the old syntax which was using a single YAML sequence to store all of the machine instructions in a block. The bundled machine instructions internally use flags like BundledPred and BundledSucc to determine the bundles, and serializing them as MI flags using the old syntax would have had a negative impact on the readability and the ease of editing for MIR files. The new syntax allows me to serialize the bundled machine instructions using a block construct without relying on the internal flags, for example: BUNDLE implicit-def dead %itstate, implicit-def %s1 ... { t2IT 1, 24, implicit-def %itstate %s1 = VMOVS killed %s0, 1, killed %cpsr, implicit killed %itstate } This commit also converts the MIR testcases to the new syntax. I developed a script that can convert from the old syntax to the new one. I will post the script on the llvm-commits mailing list in the thread for this commit. llvm-svn: 244982
