Changes in directory llvm/test/Regression/CodeGen/X86:
pic_jumptable.ll added (r1.1)
---
Log message:
Verify that jump tables are emitted to the same section as the function is,
when codegen'ing in pic mode. This fixes a miscompilation of a switch stmt
in a template, as the template goes to a non-.text section.
