toolchain/crosstool-NG: disable decimal floats

2012-05-16T08:39:32Z

Decimal floats were introduced circa gcc-4.2 or -4.3, and requires the floating-point environement fenv.h in the C library. The uClibc .config file used by crosstool-NG to build uClibc is the same as used by the internal buildroot mechanism, and explcitly disables fenv support. The quick workaround is to simply disable decimal floats in all crosstool-NG config files. In the long run, it might be better to check this situation, and/or add code and/or options in crosstool-NG to handle this (but it is much more involved, and this workaround is sane).

So we're in sync with the internal toolchain. Signed-off-by: Peter Korsgaard

crosstool-ng: fixup after copy_toolchain_lib_root api changes

2012-05-09T09:16:43Z

Commit 0729b544b3 (Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain) and e1f0804cc (external-toolchain: add support for recent Linaro toolchains) changed the interface of copy_toolchain_lib_root, but ctng wasn't updated so libraries weren't copied to the target.

ctng: use internal toolchain uClibc config, build uClibc 0.9.32

So the uClibc configurations are kept in sync between the two toolchain methods. Signed-off-by: Peter Korsgaard

toolchain/crosstool-NG: fix bundled config files

2011-08-28T07:43:21Z

Bundled config files have architecture-specific values in them, which may break if buildroot is configured with another architecture that does not forcibly set these option. For example, the bundled config files are for x86_64, and define: CT_ARCH_TUNE="generic" This comes from the BR2_GCC_TARGET_TUNE config option (in buildroot) that is set accordingly to the selected (arch,sub-arch). But if someone configures buildroot for, say, generic ARM, then the BR2_GCC_TARGET_TUNE config option is not set, and the crosstool-NG backend Makefile believes it should not be pushed down to the crosstool-NG config file. BUT... The crosstool-NG backend Makefile can not forcibly push BR2_GCC_TARGET_TUNE down to the CT-NG config file. If BR2_GCC_TARGET_TUNE is empty, the user can still set CT_ARCH_TUNE by running ctng-menuconfig. The backend Makefile already passes such values only if they are set. In the end, we can't push options as-is to the crosstool-NG config, but we MUST provide sane bundled config files, which this patch does. Signed-off-by: "Yann E.
