Hi,
I have a function with:
attributes #2 = { "no-frame-pointer-elim"="true"
"no-frame-pointer-elim-non-leaf" }
Yet when compiling it generates:
https://gist.github.com/carlokok/7c3c98d2fd8c966671f40a5ad94f19d3
(Note how it checks fFinalizer before setting up ebp).
It also has a:
.loc 36 195 7 prologue_end
before this happens
How can I get llvm to do the frame setup before prologue init (so
debuggers know what is going on)? And if not, how can a debugger know
where the frame is?
IR:
