Spec URL: http://fedorapeople.org/~brouhaha/arm/arm-none-eabi-binutils.spec SRPM URL: http://fedorapeople.org/~brouhaha/arm/arm-none-eabi-binutils-2.20-1.fc12.src.rpm Koji scratch build for Fedora 12: http://koji.fedoraproject.org/koji/taskinfo?taskID=1985797 Description: This is a Cross Compiling version of GNU binutils, which can be used to assemble and link binaries for the arm-none-eabi platform, instead of for the native %{_arch} platform.
What exact ARM sub-architecture this package is designed for? Fedora-ARM is targeted on armv5tel.
This is intended for embedded development targeting "bare metal", e.g., microcontrollers, which is why it is "arm-none-eabi" rather than "arm-something-linux". It also should be usable for systems running non-Linux operating systems that are EABI compliant, provided that the user obtains the appropriate headers and libraries. The description in the SPEC doesn't say this because I kept the generic description from the avr-binutils and arm-gp2x-linux binutils, but perhaps it is justifiable to add a paragraph explaining that it is for embedded/bare metal use. I'm working on packaging gcc, gdb, and newlib, but binutils will need to be in the package collection before I can submit them for review. (Otherwise they would fail to build due to the binutils dependency.)
I should further add that I intend this to be useful with arm7tdmi and cortex-m3 microcontrollers, although I think it should also work for other ARM architectures supported by binutils.

So, it's something like "i386" for x86 and fully compatible with armv4/armv5 and so on?
Yes, the tools accept arguments like -mthumb, -mcpu=arm7tdmi, -mcpu=cortex-m3, etc. I'm testing them by building software for an Atmel AT91SAM7L128 (arm7tdmi) and an Energy Micro EFM32G290 (cortex-m3).
I have very similar SEPC files for arm-elf-binutils, arm-elf-gcc, arm-elf-gdb packages I use for cortex-m3 microprocessors [1]. I have signed up to FAS in order to submit them [2], but it looks like you are working on it.

Closing this bug request, as I am switching to using the CodeSourcery release of Binutils, which has better ARM support than the FSF release. CodeSourcery contributes their improvements to the FSF, but they take a long time to make it into official FSF releases. *** This bug has been marked as a duplicate of bug 639661 ***
