[llvm-commits] CVS: llvm/lib/System/Unix/Signals.inc

[Reid Spencer]

Changes in directory llvm/lib/System/Unix:

Signals.inc updated: 1.10 -> 1.11
---
Log message:

Only print the stack trace if it was requested. Previously, any call into
the Signals module that registered the handlers would cause the stack trace
to be generated. Now, you must explicitly call PrintStackTraceOnErrorSignal
in order for that to happen.
