2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance

2012-06-15signal: remove sigblock, siggetmask and sigsetmaskPeter S. Mazinger
rcmd.c uses sigblock and sigsetmask, make the function static and include them directly until a rewrite is done. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-01-15libc: build abort with unwind-info for backtraceBernhard Reutner-Fischer
If backtrace support is turned on, build raise() and abort() with unwind info (fixup 4c9b7f3c21ff21c199e54bfad2fdf3445fa4573d). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
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. Impacts in terms of size are really limited Current text data bss dec hex filename 164 0 0 164 a4 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.os 164 0 0 164 a4 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.oS 220 24 4 248 f8 ./libc/stdlib/abort.os With (-fasynchronous-unwind-tables) text data bss dec hex filename 216 0 0 216 d8 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.os 216 0 0 216 d8 ./libpthread/nptl/sysdeps/unix/sysv/linux/raise.oS 280 24 4 308 134 ./libc/stdlib/abort.os Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com> Acked-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
