Hi, in my first attempt to fix a build issue I found that the order of tm files matters, would prefer to move linux-looking parts of elf.h to linux.h.
other targets that include alpha/elf.h besides linux: openbsd: provides their own STARTFILE_SPEC and ENDFILE_SPEC in later file: https://github.com/openbsd/ports/blob/master/lang/gcc/6/patches/patch-gcc_config_alpha_openbsd_h freebsd: dropped alpha in freebsd 7.0 (2008) Built trunk on netbsd/alpha (until I out of spaced with a working stage3 after two days :-)) with some extra modifications. --- gcc/config/alpha/elf.h | 26 -------------------------- gcc/config/alpha/linux.h | 26 ++++++++++++++++++++++++++ 2 files changed, 26 insertions(+), 26 deletions(-) diff --git a/gcc/config/alpha/elf.h b/gcc/config/alpha/elf.h index c109b07c5..8a435dbc0 100644 --- a/gcc/config/alpha/elf.h +++ b/gcc/config/alpha/elf.h @@ -100,32 +100,6 @@ do { \ ASM_OUTPUT_DEF (FILE, alias, name); \ } while (0) -/* Provide a STARTFILE_SPEC appropriate for ELF.
