2012-01-23Rules: Check for CROSS_COMPILE to be emptyKhem Raj
In some case where CROSS is defined to be empty we define CROSS_COMPILE ?= CROSS so at this point it will be defined but will be empty so check for the same Signed-off-by: Khem Raj <raj.khem@gmail.com>
2012-01-17buildsys: use = for --sort-section linker flagMike Frysinger

2012-01-16buildsys: fix handling of CFLAG_-W{a,l} varsMike Frysinger
Need a little indirection/delayed evaluation to handle variables with equal signs and commas in them. Reported-by: Khem Raj <raj.khem@gmail.com> 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>
2012-01-14buildsys: 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.

2011-11-26buildsys: drop manual TARGET_SUBARCH .config lookupMike Frysinger
We source the .config file, so there should be no need to manually extract it. If the sourcing doesn't work, then a lot of things break in this file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-06-11Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGSKhem Raj
UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is specified at last. So we need to change the order of these option flags Signed-off-by: Khem Raj <raj.khem@gmail.com>
2011-06-11ARM: remove sub-arch/variants selection from menuconfigYann E. MORIN
Rely on the compiler to be correctly set up to generate appropriate code for the target variant. This exposes the Thumb option, as it is no longer auto-selected. The "Use BX" no longer depends on supported CPU to be selected, so it now defaults to 'n' as it shall work by default on CPUs that do not have BX. Signed-off-by: "Yann E.

2011-06-11ARM: introduce blind options to select & force THUMB modeYann E. MORIN
Add three new blind options to set use of Thumb mode: - COMPILE_IN_THUMB_MODE - if set, CFLAGS will contain -mthumb - if unset, the compiler's default is used - HAS_THUMB - CPUS with Thumb instruction set can select this - use of BX depends on this - FORCE_THUMB - CPUs that are Thumb-only must select this - this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX Also, remove leading space in Rules.mak.

2010-09-15libubacktrace: Provide uClibc with backtrace functionsSalvatore Cro
A new shared object, libubacktrace.so.0 is added to uClibc to provide backtrace functions to support application self-debugging. This set of functions requires to dynamically load libgcc_s.so so they need to call dlopen/dlsym that are provided by libdl. For this reason they cannot be included into libc.so.0 but are provided by a new library. User application that wants to use backtrace needs to be compiled with -fexceptions option and -rdynamic to get full symbols printed and must be linked against libubacktrace.so Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-04-23change ABI_VERSION back to just include the major numberAustin Foxley
By default, GCC hard codes the name for ld.so to /lib/ld-uClibc.so.0 so our default should match that. If distribution makers want to change it, they need to change the default gcc configuration as well. Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-04-22nptl: proper soname handlingNatanael Copa

2010-02-10libc: Add a common sysdep headerCarmelo Amoroso
Add a common header file to provide macros useful in asm code: C_LABEL to construct the asm name for a C symbol cfi_xxx to generate eh_frame unwind information. Ported from NPTL branch. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-02-09nptl: sysdep headers re-factoringCarmelo Amoroso
This patch will re-factor and simplify sysdep headers handling for nptl branch. The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available only into nptl branch because are defined in sysdep.h header under the nptl folder even if they are not related to NPTL at all (this was likely due to a bad choice done at the early stage of NPTL porting). This is a required steps for integrating into master branch some asm code available in nptl branch for sh4. The main changes are described below: nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h nptl/sysdeps/sh/sysdep.h ---------------------| nptl/sysdeps/unix/sh/sysdep.h ----------------| nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----| nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -| |(merged) ---> libc/sysdeps/linux/sh nptl/sysdeps/unix/sysdep.h (deleted) Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.
