Add the .cv_fpo_stackalign directive so that we can define $T0, or the VFRAME virtual register, with it. This was overlooked in the initial implementation because unlike MSVC, we push CSRs before allocating stack space, so this value is only needed to describe local variable locations. Variables that the compiler now addresses via ESP are instead described as being stored at offsets from VFRAME, which for us is ESP after alignment in the prologue. This adds tests that show that we use the VFRAME register properly in our S_DEFRANGE records, and that we emit the correct FPO data to define it. Fixes PR38857 llvm-svn: 343603 |
