Bug ID: 16957
Summary: Generation of PLT code isn't working for ARM
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
For ARM targets on linux, revision 183966 made Fast ISel default.
Unfortunately, Fast ISel is broken in terms of applying the ARMII::MO_PLT flags
to calls in PIC mode (at least when emitting assembly); it never does this.
The normal ISel pass handles this situation correctly so a temporary local
change to disable FastISel for linux / NaCl targets is working for me right
now.
Repro: Lower any code to assembly, (PLT) will be missing from calls.
