2013-03-14Add support for the Meta architectureMarkos Chandras
Meta cores are 32-bit, hardware multithreaded, general purpose, embedded processors which also feature a DSP instruction set, and can be found in many digital radios. They are capable of running different operating systems on different hardware threads, for example a digital radio might run RTOSes for DAB decoding and audio decoding on 3 hardware threads, and run Linux on the 4th hardware thread to manage the user interface, networking etc. HTPs are also capable of running SMP Linux on multiple hardware threads.

2012-06-15Rules.mak: change the way -include is usedPeter S. Mazinger
Other compilers do not expect absolute path after -include, they want to find the included file by path search (-I). While there, prefer $(TARGET_ARCH) before common path. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-06-13buildsys: clean up libubacktrace linker script handlingKevin Cernekee
Currently, the installed libubacktrace linker script entry always uses HARDWIRED_ABSPATH semantics, even if HARDWIRED_ABSPATH is disabled: $ grep GROUP $PREFIX/mipsel-linux-uclibc/sys-root/usr/lib/libc.so GROUP ( libc.so.0 uclibc_nonshared.a AS_NEEDED ( ld-uClibc.so.0 ) ) GROUP ( AS_NEEDED ( /lib/libubacktrace.so.0 ) ) This causes problems when building a non-sysroot toolchain. Move the AS_NEEDED insertion into libc/Makefile.in, and add a case to the HARDWIRED_ABSPATH substitution command so libubacktrace is handled the same way as the other libraries listed in the script.

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>
