* libc: build abort with unwind-info for backtraceBernhard Reutner-Fischer2012-01-152-0/+4
| | | | | | | 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>
* libc: allow to backtrace out of abort callCarmelo Amoroso2012-01-132-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso2011-11-231-8/+0
| | | | | | | | | | | | On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.

* inet: build all res_* and ns_* functions conditionallyDaniel Mack2011-08-261-3/+2
| | | | | | | | | | | | This patch changes the build system so that all DNS resolver related functions (ie, those starting with dn_, ns_ and res_) are only built if UCLIBC_HAS_RESOLVER_SUPPORT is set. This means that the libc will lack support for things that existed in the library before unless this new config option is set. On the other hand, if users really need support for resolver functions, they now get a more complete set, and the library is smaller than before it is deselected.
