From 799672a6414c7056d24213041bb3f0a12e9a9a66 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Sun, 14 Sep 2008 16:21:07 +0000 Subject: Introduce a new EXPERIMENTAL feature: BARE_METAL. 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(-) --- config/libc.in | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) (limited to 'config/libc.in') diff --git a/config/libc.in b/config/libc.in index a8cf28ce..d5647520 100644 --- a/config/libc.in +++ b/config/libc.in @@ -1,5 +1,14 @@ # C library options +config LIBC + string + default "none" if BARE_METAL + default "glibc" if LIBC_GLIBC + default "eglibc" if LIBC_EGLIBC + default "uClibc" if LIBC_UCLIBC + +if !
