Bug #: 13504
Summary: INLINEASM doesn't implement mayLoad and mayStore
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Created attachment 8981
--> http://llvm.org/bugs/attachment.cgi?id=8981
Example code
mayLoad and mayStore always return false for INLINEASM instructions, even when
there is a memory constraint.
One consequence is that post-RA instruction scheduler builds incorrect graph
for an example from attachment (it lacks the required MOV32mr->INLINEASM
dependence).
