[PATCH] D50694: [Sparc] Give the option to use the OS reserved global registers

[Daniel Cederman via Phabricator via llvm-commits]

dcederman added a comment.

Added attributes to prevent %g2-%g5 from being used as scratch register or to allow the use of %g5-%g7 as scratch registers. %g5 is reserved by default for 32-bit but not for 64-bit.

Renamed the field names to ReserveRegG*.

Added error messages if the TLS model or stack protector tries to use %g7 and it is not reserved.

EmitFunctionBodyStart now checks the list of actually reserved registers to output the correct register annotations.
