2012-06-15cleanup fork()Peter S. Mazinger
Keep only fork (and it's hidden variant) and __libc_fork. Common __libc_fork prototype in unistd.h. Get rid of __fork, by changing HIDDEN_JUMPTARGET(__fork) to use fork I can't see the reason to have fork() in libpthread, but kept it for now making __fork static in these files.

2012-06-15move *longjmp related prototypes to setjmp.hPeter S. Mazinger
Provide common prototypes for __longjmp, __libc_longjmp, __libc_siglongjmp _longjmp_unwind, __libc_unwind_longjmp in setjmp.h in preparation for use in LT new Add __longjmp to h8300 and i960 Make common longjmp.c good for NPTL Guard _longjmp_unwind use in sh's longjmp.c for NPTL (I think sh could use the common one) Remove unneeded attribute_noreturn, prototype provides it already Signed-off-by: Peter S.

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>

2012-01-15libc: 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>

2011-02-25nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso
ARM disables by default the support for ASM CFI directives. Anyway using an old version of binutils that does not support some new pseudo-op, the build fails as below: AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages: libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections' The problem is that the .cfi_sections pseudo should be wrapped by a macro that expands to nothing when the CFI is off.

My change a49b3a18e463cbe8c94c41501e386e7f4c61609e fixed two Unwind_Resume calls to go via PLT to avoid text relocations for PIC builds. However, it looks the reason for upstream not using PLT calls is that ebx gets clobbered. So we need to reload it.

implementation" This reverts commit 0c468129356f5ce6780e7369c271d74631ae03ba.
