* gdb: adjust behavior when thread debug is not availableThomas Petazzoni2012-11-031-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | When an external toolchain without thread debug is used, the gdb package can be selected, but no version can be choosen, since none match any of the requirements. This leads Buildroot to try to build gdb for the target without a version being defined, as in the following build log: http://autobuild.buildroot.org/results/84e8fd2df0cc22448052a572c2e9a6e03dd137eb/build-end.log To fix this, we adjust the dependencies of the BR2_PACKAGE_GDB option so that the package as a whole is not selectable when the required conditions are not met. Basically, we have the choice of: * Having a toolchain that supports thread debugging, which is needed for gdb >= 7.x * Having BR2_DEPRECATED enabled, which allows gdb 6.8 to be selected, which doesn't require thread debugging * Using bfin, since this architectures has a special old gdb version Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* toolchain: make external toolchain the default for AArch64Thomas Petazzoni2012-11-021-2/+2
| | | | | | | | | | Our internal toolchain backend does not yet have support for AArch64, and Crosstool-NG also does not have support for AArch64 at the moment (though it should be coming quickly since the Linaro AArch64 toolchain is generated with a modified Crosstool-NG version).

* toolchain/crosstool-ng: vendor part of tuple should be 'buildroot'Thomas Petazzoni2012-10-181-1/+1
| | | | | | | | | | | | | | | | | | | Since 11017f081fc5b034e680d89eaea729c19f450e01, the Crosstool-ng backend generates toolchains that have a prefix inconsistent with what Buildroot expects. Buildroot expects a "buildroot" vendor name, while Crosstool-NG builds toolchain with the "unknown" vendor name. This is causing build failure such as: http://autobuild.buildroot.org/results/15b2c0e50a81b86dd13af684c9254df2bc0df8de/build-end.log Fix this by changing the vendor part of the tuple used by Crosstool-NG to "buildroot".

| | | | | | | | | | | | | | As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened. Therefore, drop support for this architecture. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: me Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | | | | BR2_ARM_TYPE is a hidden configuration option that is only used for the configuration of uClibc, therefore, we move it from target/Config.arch.in to toolchain/uClibc/Config.in. We also add a comment that explains that this stuff is only useful for uClibc <= 0.9.32. Starting from 0.9.33, uClibc build process simply uses the compiler flags to find the ARM processor that should be used. So, someday, we'll be able to remove this.

* Clarify MIPS ABIs supportThomas Petazzoni2012-09-041-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Practically speaking, MIPS has three useful ABIs: * o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset of the instruction set. * n32 is for 64-bits CPUs only. It has 32-bits pointers and long integers. * n64 is for 64-bits CPUs only. It has 64-bits pointers and long integers. See http://www.linux-mips.org/wiki/MIPS_ABI_History and http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more details. So, this commit reworks the Buildroot MIPS support by: * Add separate mips64/mips64el top-level architectures. * Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency with BR2_MIPS_OABI32. * Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency with BR2_MIPS_OABI32. * Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64, since those ABIs are valid on 64-bits CPUs only. * Removing the o64 ABI, which is practicaly never used. * Removing the "none" ABI, which really doesn't make sense. * Introduce the mips64 and mips64el architecture names when a 64-bits MIPS ABI is choosen. This will fix build issue like http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log where gmp was confused by the fact of having a 32 bits architecture (detected by the mips- architecture part of the tuple) but 64 bits integer size when compiling. * Adjust the uclibc.mk logic to support the new mips64/mips64el architecture names, and take into account the renaming of the ABI options. This has been build tested by generating Buildroot toolchains and compiling a few packages for MIPS o32, MIPS n32 and MIPS n64. This work is originally based on prior work done by Gustavo Zacarias.

* toolchain-external: do not allow the user to select hard/soft floatThomas Petazzoni2012-08-011-1/+4
| | | | | | | | | | | | | | | | | Commit ba92d6ef68eeb37ba435648fcfbd1dbe13212e6d made hard float the default when Cortex-A8 and Cortex-A9. The problem it was trying to fix is that the newer Linaro toolchains (2012.05 and 2012.06) are hard-float, so the default selection of soft-float enabled on ARM doesn't work for those toolchains. Unfortunately, not selecting soft-float causes problems with the Crosstool-NG backend at the moment. As an intermediate solution, make the soft float option disappear when using external toolchain: the toolchain will decide by itself whether to generate hard float or soft float code.

| | | | | | | | | | | | | | Cortex-A8 and Cortex-A9 ARM cores are guaranteed to provide a hardware floating point unit, so there's no reason to default to software floating point for them. More importantly, the newest Linaro toolchains are hard float toolchains, so basically an user choosing those toolchains and leaving the default option of software float would run in compilation issues. So let's make hard float the default for Cortex-A8 and Cortex-A9. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* toolchain-external: adjust logic to support Linaro 2012.05Thomas Petazzoni2012-07-221-2/+2
| | | | | | | | | | | | | | | | | | | | | The check_glibc function verifies that the C library of the external toolchain is glibc. To do so, it verified that a file matching ld-linux*.so.* or ld.so.* was found in the lib/ directory of the toolchain's sysroot. However, with the Linaro 2012.05 toolchain, the lib/ directory contains two links named ld-linux-armhf.so.3 and ld-linux.so.3, which means that the first ld-linux*.so.* wildcard expression expands to two files, which generates a syntax error for the "test" program. We replace that with a more elaborate find+wc combination to determine whether at least one matching file is present. The check_arm_abi function verifies the ABI of an ARM toolchain. For EABI, it tested that the target name ends with eabi. However, with Linaro 2012.05, the tuple is now arm-linux-gnueabihf (for hard float), so we have to adjust the logic to accept this additional "hf" specification in the tuple.
