[llvm-commits] CVS: llvm/autoconf/configure.ac

[David Greene]

Changes in directory llvm/autoconf:

configure.ac updated: 1.271 -> 1.272
---
Log message:

Add support for building with _GLIBCXX_DEBUG.  New configure option
--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time.  Currently it only
turns on _GLIBCXX_DEBUG.  Other expensive debugging checks added later
should be controlled by this configure option.

This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.
