[llvm-commits] Slot alignment

[Mon P Wang]

Hi,

The following small patch is to fix a problem when we have to  
EmitStackConvert.  It is possible that two types of the same size may  
have different alignment (e.g., users may specify a stricter alignment  
than native or vector types may have stricter alignment than a scalar  
of the same size).  If one ever tries to do stack convert of this, we  
create a stack slot with the alignment of the destination and we can  
generate a load/store with greater alignment than the stack slot that  
we have created.  The following patch generates a StackSlot with the  
minimum alignment necessary for both the source and the destination  
type.  If you have any comments, please let me know.
