Bug ID: 85905
Summary: cannot build for netbsd/alpha (with patch)
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: coypu at sdf dot org

move linux specfile stuff to linux file.
when I build trunk I get in libgomp/config.log cannot create executables:
configure:3725: checking for C compiler default output file name
configure:3747: /tmp/build/./gcc/xgcc -B/tmp/build/./gcc/
-B/usr/local/alpha--netbsd/bin/ -B/usr/local/alpha--netbsd/lib/ -isystem
/usr/local/alpha--netbsd/include -isystem /usr/local/alpha--netbsd/sys-include
--sysroot=/home/fly/alpha/destdir.alpha/ -g -O2 -mieee conftest.c >&5
/home/fly/alpha/tooldir.NetBSD-8.99.17-amd64/alpha--netbsd/bin/ld: cannot find
crt1.o: No such file or directory
collect2: error: ld returned 1 exit status
I include two tm files that have effect on STARTFILE_SPEC definition.
alpha/elf.h:
#undef STARTFILE_SPEC
#ifdef HAVE_LD_PIE
#define STARTFILE_SPEC \
"%{!shared: %{pg|p:gcrt1.o%s;pie:Scrt1.o%s;:crt1.o%s}}\
crti.o%s %{static:crtbeginT.o%s;shared|pie:crtbeginS.o%s;:crtbegin.o%s}"
This is good for linux probably but I don't have crt1.o on netbsd.
netbsd-elf.h
#define NETBSD_STARTFILE_SPEC \
"%{!shared: \
%{pg:gcrt0%O%s} \
%{!pg: \
%{p:gcrt0%O%s} \
%{!p:crt0%O%s}}} \
%:if-exists(crti%O%s) \
%{static:%:if-exists-else(crtbeginT%O%s crtbegin%O%s)} \
%{!static: \
%{!shared:crtbegin%O%s} %{shared:crtbeginS%O%s}}"
#undef STARTFILE_SPEC
#define STARTFILE_SPEC NETBSD_STARTFILE_SPEC
This should work for all netbsd targets.
Attached is a patch to move alpha/elf.h definitions to linux.
I've previously sent it to gcc-patches but it didn't work so well. I'll resend.

I'm not very good at cross building and relying on netbsd's existing cross
tools to do these checks (binutils etc.). I don't know how to set it up for
openbsd, and they don't provide a similar toolchain. I have no alpha hardware
of my own but I tested this on someone's machine then.
