2012-01-27libc_arm: avoid multiple version of __aeabi_unwind_cpp_pr dummy codeCarmelo Amoroso
Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code. Just add it to uclibc_nonshared.a archive and share it. This fixes build issue with static linking of application due to multiple symbol definition in libgcc_eh-a and libpthread.a or librt.a Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

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>

2012-01-16buildsys: skip compiler flag checking for clean targetsMike Frysinger
As suggested by Bernhard, there is no point in evaluating the compiler's flag availability when cleaning, so skip things in that case. If there are variables that change targets based on the flags, then things are already broken and need fixing independently. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-01-15buildsys: simplify include_clean greatlyMike Frysinger
Since we want to clean out all the headers we symlinked into include/, just use `find` to locate all the symlinks for us. This simplifies it greatly, and actually fixes bugs where we build for one arch, switch to another, and then do a clean but the previous arch headers are left behind.

2012-01-15buildsys: fix detection of silent makeMike Frysinger
The MAKEFLAGS variable contains all the flags without the leading dash. From the GNU make manual: This variable is set up automatically by make to contain the flag letters that make received. Thus, if you do ‘make -ks’ then MAKEFLAGS gets the value ‘ks’. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-01-15tests: skip redundant -Wstrict-prototypes setupMike Frysinger
We inherit the top-level Rules.mak which sets up this flag for us, so just rely on that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-01-14linuxthreads/signals: do not restore handler for invalid signalMarkos Chandras
Invalid signals have no handlers so when trying to restore the old handler to a bad signal a SIGSEGV occurs. This is because the library tries to store the old handler to an invalid memory area where it things the bad signal lives.

2012-01-14buildsys: cache build flags in varsMike Frysinger
Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags. Add some helpers to automate the process of setting up variables to cache the result of tests, as well as the checking of an already set flag. Now `make clean` takes like 2 seconds on my system.

2012-01-13libubacktrace: use -asynchronous-funwind-tables rather than -funwind-tablesCarmelo Amoroso
From gcc documentation, we can read: " ... -fasynchronous-unwind-tables Generate unwind table in dwarf2 format, if supported by target machine. The table is exact at each instruction boundary, so it can be used for stack unwinding from asynchronous events (such as debugger or garbage collector) ..." So it seems better rather than using -funwind-tables (glibc seems to prefer -fasynchronous-unwind-tables).

2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.
