2012-03-11__stdio_WRITE: make code more readable. No code changesDenys Vlasenko
Pulled assignments out of ifs. do {...} while (1); is a weird method of writing "loop forever", thus rewrote it. No code changes: objdump output is the same. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2012-03-05librt: refactor source selectionMike Frysinger
Should make adding more knob control simpler as people only need to modify one variable now (librt_filter_SRC). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-02-07tests:math: fix build of math tests for SH4Carmelo Amoroso
Rename libm-test-ulps-sh4 to libm-test-ulps-sh as the ULPS file is expected to match pattern libm-test-ulps-$(TARGET_ARCH). Indeed "sh4" is the TARGET_SUBARCH. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2012-02-07tests:libdl: add a new test for symbol scope issue in dlcloseFilippo ARCIDIACONO
Test case to trigger an issue raised by the new symbol scope design, that was erroneously removing local symbol scope from the global one too early while dl-closing a shared library.

2012-01-23libc: fix signal handling in system()Richard Braun
When built without NPTL support (or for a sparc target), the system() function doesn't conform to its specification. Namely, it uses signal() to install/save/restore signal handlers, which may break applications using custom handlers installed with sigaction(). In addition, it resets the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may result in "lost" signals if a custom handler was installed. Fix system() by replacing uses of signal() with appropriate calls to sigaction() and sigprocmask(). Signed-off-by: Richard Braun <rbraun@sceen.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
