- Subject: [PATCH] Check for availability of backtrace() for boehm-gc on uClibc
Hi,
uClibc does not currently have support for backtrace(). Iff support
would be added, then we would hint that via __UCLIBC_HAS_BACKTRACE__.
We are carrying this snippet since about 4.0.0 now. I fear that boem-gc
upstream != gcc, though?
boehm-gc/ChangeLog:
2008-10-07 Bernhard Reutner-Fischer <>
* include/gc.h (GC_HAVE_BUILTIN_BACKTRACE): Add check for
__UCLIBC_HAS_BACKTRACE__.
Ok for trunk?
