From baa67289df42b1b994092b8312148a6f9e172274 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Wed, 18 Feb 2004 08:04:51 +0000 Subject: Alexandre Oliva writes: This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem. --- extra/Configs/Config.frv | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 extra/Configs/Config.frv (limited to 'extra/Configs/Config.frv') diff --git a/extra/Configs/Config.frv b/extra/Configs/Config.frv new file mode 100644 index 000000000..1210ad92f --- /dev/null +++ b/extra/Configs/Config.frv @@ -0,0 +1,32 @@ +# +# For a description of the syntax of this configuration file, +# see extra/config/Kconfig-language.txt +# + +config HAVE_ELF + bool + select HAS_FPU + select ARCH_BIG_ENDIAN + select ARCH_HAS_NO_MMU + default y + +config TARGET_ARCH + string + default "frv" + +config ARCH_CFLAGS + string + +config ARCH_LDFLAGS + string + +config LIBGCC_CFLAGS + string + +config HAVE_DOT_HIDDEN + bool + default y + +config UCLIBC_COMPLETELY_PIC + bool + default y -- cgit v1.2.3
