Bug ID: 16320
Summary: ARM FastISel disabled for Thumb2 on non-iOS targets
Product: libraries
Version: trunk
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
lib/Target/ARM/ARMFastISel.cpp:ARM::createFastISel enables FastISel in the
following circumstances:
bool UseFastISel = false;
UseFastISel |= Subtarget->isTargetIOS() && !Subtarget->isThumb1Only();
UseFastISel |= Subtarget->isTargetLinux() && !Subtarget->isThumb();
UseFastISel |= Subtarget->isTargetNaCl() && !Subtarget->isThumb();
Thumb2 FastISel has issues with at least some relocations as well as with MI
validation, but should otherwise be able to use FastISel.
