Puyan Lotfi	43e94b15ea	Followup on Proposal to move MIR physical register namespace to '$' sigil. ... Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922	2018-01-31 22:04:26 +00:00
Matthias Braun	333e468d15	MIRParser: Use dot instead of colon to mark subregisters ... Change the syntax to use `%0.sub8` to denote a subregister. This seems like a more natural fit to denote subregisters; I also plan to introduce a new ":classname" syntax in upcoming patches to denote the register class of a vreg. Note that this commit disallows plain identifiers to start with a '.' character. This shouldn't affect anything as external names/IR references are all prefixed with '$'/'%', plain identifiers are only used for instruction names, register mask names and subreg indexes.

Matthias Braun	538859cca3	llc: Add support for -run-pass none ... This does not schedule any passes besides the ones necessary to construct and print the machine function. This is useful to test .mir file reading and printing. Differential Revision: http://reviews.llvm.org/D22432 llvm-svn: 275664	2016-07-16 02:24:59 +00:00
