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/target.in | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'config/target.in') diff --git a/config/target.in b/config/target.in index b5c7af12..bd7b725b 100644 --- a/config/target.in +++ b/config/target.in @@ -28,6 +28,19 @@ config TARGET_LDFLAGS comment "General target options" +config BARE_METAL + bool + prompt "Bare metal (EXPERIMENTAL)" + default n + depends on EXPERIMENTAL + help + Say 'y' here if you want a simple C compiler with no C library. + + You probably want to say 'y' here if you plan to use your compiler + to build only kernels or bootloaders + + 'Bare metal' also refer to those programs that run without any kernel. + choice bool prompt "Target architecture:" -- cgit v1.2.3
