* Forward parameter options as '-option=parameter'.Mikhail Glushenkov2010-02-132-3/+3
| | | | | | | Some tools do not like the '-option parameter' form. Should this be configurable? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96130 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR6283.Jakob Stoklund Olesen2010-02-133-19/+298
| | | | | | | | | | | When coalescing with a physreg, remember to add imp-def and imp-kill when dealing with sub-registers. Also fix a related bug in VirtRegRewriter where substitutePhysReg may reallocate the operand list on an instruction and invalidate the reg_iterator. This can happen when a register is mentioned twice on the same instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96072 91177308-0d34-0410-b5e6-96231b3b80d8

It means targets which perform dynamic stack alignment would know whether it is required and whether frame pointer register cannot be made available register allocation.

* Enable the inlinehint attribute in the Inliner.Jakob Stoklund Olesen2010-02-131-13/+12
| | | | | | | | | | | | | | | | | | | | Functions explicitly marked inline will get an inlining threshold slightly more aggressive than the default for -O3. This means than -O3 builds are mostly unaffected while -Os builds will be a bit bigger and faster. The difference depends entirely on how many 'inline's are sprinkled on the source. In the CINT2006 suite, only these tests are significantly affected under -Os: Size Time 471.omnetpp +1.63% -1.85% 473.astar +4.01% -6.02% 483.xalancbmk +4.60% 0.00% Note that 483.xalancbmk runs too quickly to give useful timing results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96066 91177308-0d34-0410-b5e6-96231b3b80d8
