* Coding style fixes.Akira Hatanaka2011-06-071-3/+4
| | | | | | | | | - Fix indentation. - Move comments. - Fit lines in 80 columns. - Remove dead code. llvm-svn: 132724
* Add test case for C++ exception handling and fix the following mistakes in ↵Akira Hatanaka2011-06-071-30/+60
| | | | | | | | | | | | | | | | | | MipsFrameLowering::emitPrologue: - cfi directives are not inserted at the right location or in the right order. - The source MachineLocation for the cfi directive that changes the cfa register to $fp should be MachineLocation::VirtualFP. - A PROLOG_LABEL that marks the beginning of cfi_offset directives for callee-saved register is emitted even when no callee-saved registers are saved. - When a callee-saved double precision register is saved, two cfi_offset directives, one for each of the paired single precision registers, should be emitted. llvm-svn: 132703

* Change StackDirection from StackGrowsUp to StackGrowsDown.Akira Hatanaka2011-05-231-108/+18
| | | | | | | | | | | | | | | | The following improvements are accomplished as a result of applying this patch: - Fixed frame objects' offsets (relative to either the virtual frame pointer or the stack pointer) are set before instruction selection is completed. There is no need to wait until Prologue/Epilogue Insertion is run to set them. - Calculation of final offsets of fixed frame objects is straightforward. It is no longer necessary to assign negative offsets to fixed objects for incoming arguments in order to distinguish them from the others. - Since a fixed object has its relative offset set during instruction selection, there is no need to conservatively set its alignment to 4. - It is no longer necessary to reorder non-fixed frame objects in MipsFrameLowering::adjustMipsStackFrame. llvm-svn: 131915
