...he ARM Architecture" and my best guess has been to inspect .ARM.attributes in the elf-dump's section data, but both LLVM and GCC use "aeabi" for the vendor name. I've found several ways to distinguish the two (such as a magic number where GCC uses ELFOSABI_SYSV and LLVM uses ELFOSABI_LINUX), but hoping for something more reliable, like a toolchain signature. Is there anything like that? Thanks, Greg

...quot;, etc). Amara, Maybe another thing to add to your attributes patch, adding some vendor specific info to it (like clang/version, llvm/version, integrated-as, etc)? > I've found several ways to distinguish the two (such as a magic number > where GCC uses ELFOSABI_SYSV and LLVM uses ELFOSABI_LINUX), but hoping > for something more reliable, like a toolchain signature. I wouldn't rely on that. I'm not sure what's your objective, but in the past when I had to test separate binaries generated from integrated-as and compare to GAS generated objects I just had different names for...

This series updates the boot protocol to 2.07 and uses it to implement paravirtual booting. This allows the bootloader to tell the kernel what kind of hardware/pseudo-hardware environment it's coming up under, and the kernel can use the appropriate boot sequence code. Specifically: - Update the boot protocol to 2.07, which adds fields to specify the hardware subarchitecture and some
