* toolchain: add powerpc SPE ABI supportGustavo Zacarias2012-01-071-0/+5
| | | | | | | | | | | | | | | | | Add the ability for buildroot to build an SPE ABI enabled toolchain. This is mandatory for e500v1/v2 cores since they don't support classic FPU mode as the e500mc does. Useful for Freescale's PowerQUICC III and single/dual-core QorIQ line of processors. The new TARGET_ABI variable is used rather than TARGET_CFLAGS for uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a good example being -mthumb for ARM.

* toolchain: Add support for --with-cpuKonrad Eisele2010-11-251-0/+3
| | | | | | | | Add support for gcc configuration switch --with-cpu. Uses newly added BR2_GCC_TARGET_CPU from the target config. Signed-off-by: Konrad Eisele <konrad@gaisler.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* gcc: remove option on SJLJ exceptionsThomas Petazzoni2010-07-281-4/+0
| | | | | | | | | | | This is a very advanced option, and it seems, according to http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't really interesting. Users really interested by this can always use the BR2_EXTRA_GCC_CONFIG_OPTIONS is they want. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* toolchain: remove redundant and incorrect --with-build-time-tools optionThomas Petazzoni2010-07-271-2/+0
| | | | | | | | | | | This option is already part of the gcc configure options through the BR2_CONFIGURE_BUILD_TOOLS variable (in toolchain/Makefile.in). Additionnally, the value that was passed in the AVR32 specific case was incorrect: it was $(STAGING_DIR)/$(REAL_GNU_TARGET_NAME)/bin instead of $(STAGING_DIR)/usr/$(REAL_GNU_TARGET_NAME)/bin.

* target-gcc: Get rid of TARGET_GCC_FLAGSThomas Petazzoni2010-07-271-5/+0
| | | | | | | This variable is used only once, so let's just hardcode its value at its call site. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* toolchain/gcc: cleanup softfloat selectionPeter Korsgaard2010-07-091-5/+1
| | | | | | | We don't have a BR2_SOFT_FLOAT_FP option, and -mfloat-abi should also be used for big endian ARM. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Remove BR2_PREFER_IMAThomas Petazzoni2010-04-111-4/+0
| | | | | | | This option is barely used, no-one is maintaining it or extending it. So let's remove it. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* gcc: improve configuration for snapshot versionsThomas Petazzoni2009-12-141-1/+1

* toolchain/gcc: don't enable libssp supportPeter Korsgaard2009-04-221-2/+0
| | | | | It's broken anyway as we don't install libssp* into TARGET_DIR, and we should use the SSP support in uClibc if we want stack protection.

* gcc: only use -mfloat-abi for ARM, use -msoft-float for other archsPeter Korsgaard2008-08-221-0/+4
| | | | Patch by Wade Berrier.
* toolchain: also use arch/tune/abi options when softfloat is enabledPeter Korsgaard2008-06-061-1/+2
| | | | | The ifeq/endif nesting was wrong, so arch/tune/abi options where only set in the non-softfloat case.

| | | | | | | | | | | | | | | Hi Eric, I writing privately since I have not heard from Mike for 2 weeks about a one line patch to the gcc Makefile.in to allow the extra gcc options to be passed in. The patch is below and without it -- gcc extra's like --with-cpu=xscale do not work. The patch is as follows:

| | | | | | | | | TARGET_LANGUAGES wasn't being set correctly if you enable GCJ or C++ in the buildroot config. It looks like INSTALL_LIBSTDCPP and INSTALL_LIBGCJ were renamed to BR2_INSTALL_... in the config system, but not in the gcc and ccache makefiles. -Kristian
