2015-02-12Update MIPS configuration rules.Steve Ellcey
Add a configuration choice for the NaN format on MIPS (either the standard (legacy) format or the newer IEEE 2008 format. Change how CPU_LDFLAGS are set for MIPS. Use the same value as CPU_CFLAGS since CC is used to do linking. This ensures consistency between compiles and links and adds support for N32 ABI to linking.

2014-02-15buildsys: Add MIPS64R2 supportSteve Ellcey

2013-11-13buildsys: check LDFLAGS through driverBernhard Reutner-Fischer
We run the linker through the compiler-driver, so we have to check linker flags through the driver, too. Otherwise we might check $LD's flags while we will run $CC's linker and those might be different beasts. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-07-26Rules.mak: Fix setting arch native bitGustavo Zacarias
fix breakage from 603af30d Removing the whitespace from findstring for 64 bit architectures has bad consequences since powerpc would be a match in powerpc64 and sparc would also be a match in sparc64. That doesn't make them 64 bits in reality causing general breakage.

2013-07-19Rules.mak: MIPS64: Select correct interpreterMarkos Chandras
gcc (eg 4.7.3) hardcodes the MIPS64 interpreters like this: (see gcc/config/linux.h and gcc/config/mips/linux64.h) o32: UCLIBC_DYNAMIC_LINKER "/lib/ld-uClibc.so.0" n32: UCLIBC_DYNAMIC_LINKERN32 "/lib32/ld-uClibc.so.0" n64: UCLIBC_DYNAMIC_LINKER64 "/lib/ld64-uClibc.so.0" The existing check for MIPS64 in uClibc is wrong because it does not respect the selected ABI We fix this by explicitely checking the selected ABI instead of the selected MIPS variant.

2013-05-19i386: punt all config options that just control -marchMike Frysinger
You can set these yourself in your CFLAGS, and our list is incomplete and pointless (we agreed some time ago to stop doing this). We keep around CONFIG_[3456]86 because it is used to select between different optimized subdirs of handcoded assembly. Also take this opportunity to up the default to i686. If you're using an older cpu, then you can handle changing this yourself. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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.

2012-06-13buildsys: 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.

Running `make clean` atm takes like 20 seconds because every subdir re-evaluates all the toolchain flags.

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.

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.
