[LLVMdev] Query Regarding instruction ordering of passive nodes
...y generated assembly code. Is this by design intentionally?
If so, why ?
Tried updating the debugloc info for constant sdnodes as per http://llvm.org/bugs/show_bug.cgi?id=13269 by just modifying for getConstant APIs
It results in duplicate debug location info for same line numbers as attached in gdb11531_getConstant_modified.s
In addition, passive nodes are omitted from scheduled during instruction scheduling such that they are free to be placed anywhere while generating the instruction sequence. Is this related with above problem of debug location ?
The list of passive nodes are :-
ConstantSDNode
ConstantFPSDNode...
