This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library. Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal. Move the compiler build script to its own sub-directory. Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal. Update the ARM target tuples to enable bare-metal targets. Add two ARM bare-metal samples. Add latest Linux kernel versions. /trunk/scripts/build/kernel/none.sh | 77 6 71 0 +---- /trunk/scripts/build/cc/gcc.sh | 58 41 17 0 ++- /trunk/scripts/build/libc/none.sh | 513 9 504 0 +----------------------------- /trunk/scripts/crosstool.sh | 17 9 8 0 + /trunk/scripts/functions | 6 4 2 0 + /trunk/scripts/showSamples.sh | 6 3 3 0 /trunk/samples/arm-unknown-elf/crosstool.config | 225 225 0 0 +++++++++++++ /trunk/samples/arm-unknown-eabi/crosstool.config | 223 223 0 0 +++++++++++++ /trunk/config/kernel/linux_headers_install.in | 64 27 37 0 ++-- /trunk/config/kernel.in | 9 8 1 0 + /trunk/config/toolchain.in | 1 1 0 0 + /trunk/config/cc/gcc.in | 3 3 0 0 + /trunk/config/debug/dmalloc.in | 1 1 0 0 + /trunk/config/debug/gdb.in | 4 3 1 0 + /trunk/config/debug/strace.in | 1 1 0 0 + /trunk/config/debug/duma.in | 1 1 0 0 + /trunk/config/cc.in | 8 8 0 0 + /trunk/config/target.in | 13 13 0 0 + /trunk/config/binutils.in | 1 1 0 0 + /trunk/config/gmp_mpfr.in | 1 1 0 0 + /trunk/config/libc.in | 17 11 6 0 + /trunk/arch/arm/functions | 3 1 2 0 - 22 files changed, 600 insertions(+), 652 deletions(-)

gcc is the full-blown GNU compiler. This is what most people will choose.
|
|
|
|
gcc supports many languages, a powerful code parser, optimised binary
|
|
output, and lots of other features.

Enter here a comma-separated list of languages that you know your compiler

|
supports, besides those listed above.

|
Eg. gcc-4.1+ has a toy programming language, treelang. As it is not usefull
|
|
in real life, it is not available in the selection above.
