2013-03-07Remove PIPE_BUF Linux-specific codeSiddhesh Poyarekar2-24/+0
Fixes BZ #12723 The variable pipe buffer size does nothing to the value of PIPE_BUF, since the number of bytes that are atomically written is still PIPE_BUF on Linux.

2013-02-25Use long wherever possible in mpa.cSiddhesh Poyarekar1-31/+39
Using long throughout like powerpc does is beneficial since it reduces the need to switch to 32-bit instructions. It gives a very minor performance improvement.

2013-02-18unify xmalloc prototypes & friendsMike Frysinger1-7/+1
These prototypes are duplicated in many places. Add a dedicated header for holding prototypes for program-specific functions to avoid that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-02-18C++11 thread_local destructors supportSiddhesh Poyarekar10-0/+30
This feature is specifically for the C++ compiler to offload calling thread_local object destructors on thread program exit, to glibc. This is to overcome the possible complication of destructors of thread_local objects getting called after the DSO in which they're defined is unloaded by the dynamic linker. The DSO is marked as 'unloadable' if it has a constructed thread_local object and marked as 'unloadable' again when all the constructed thread_local objects defined in it are destroyed.

Consolidate code to search for an address within a DSO.
