Bug ID: 44167
Summary: libunwind assumes all powerpc platforms have altivec
and FPU
Product: Runtime Libraries
Version: trunk
Hardware: Other
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: libunwind
Assignee: unassignedb...@nondot.org
Reporter: chmeeed...@gmail.com
CC: llvm-bugs@lists.llvm.org
UnwindRegistersSave.S includes unconditional saving and loading of floating
point registers and altivec registers. However, not all PowerPC platforms have
FPU or Altivec. The PowerPC e500 uses a non-standard FPU, the SPE, which uses
the GPRs, and has no altivec. The PowerPC e500mc and e5500 have a FPU but no
Altivec.
