Now that there can be multiple hint registers from targets, it doesn't make sense to have a function that returns 'the' preferred register. llvm-svn: 169190

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite. This fix does the following: - make sure all short options are treated as "int" - make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired - fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates - fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value llvm-svn: 169189

Targets can provide multiple hints now, so getRegAllocPref() doesn't make sense any longer because it only returns one preferred register. Replace it with getSimpleHint() in the remaining heuristics. This function only llvm-svn: 169188

This change tries to simmplify E1 = " X >> C1 << C2" into : - E2 = "X << (C2 - C1)" if C2 > C1, or - E2 = "X >> (C1 - C2)" if C1 > C2, or - E2 = X if C1 == C2. Reviewed by Nadav. Thanks! llvm-svn: 169182

The TargetRegisterInfo::getRegAllocationHints() function is going to replace the existing mechanisms for providing target-dependent hints to the register allocator: ResolveRegAllocHint() and getRawAllocationOrder(). The new hook is more flexible because it allows the target to provide multiple preferred candidate registers for each virtual register, and it is easier to use because targets are not required to return a reference to a constant array like getRawAllocationOrder(). An optional VirtRegMap argument can be used to provide target-dependent hints that depend on the provisional assignments of other virtual registers. llvm-svn: 169154
