From 13ac54d1ca89d8a50b996cd26fefb9d836461a74 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 1 Aug 2003 19:12:52 +0000 Subject: [PATCH] Since HPUX now exists for Itanium, we should decouple the assumption that OS=hpux is the same as CPU=hppa. First steps at doing this. With these patches, we still work on hppa with either gcc or HP's cc. We might work on hpux/itanium with gcc, but I can't test it. Definitely will not work on hpux/itanium with non-gcc compiler, for lack of spinlock code. --- configure | 2 +- configure.in | 4 +-- src/backend/port/hpux/tas.c.template | 4 +++ src/backend/port/tas/{hpux.s => hpux_hppa.s} | 0 src/include/port/hpux.h | 29 +++++++++++++++----- src/include/storage/s_lock.h | 17 ++++++------ 6 files changed, 38 insertions(+), 18 deletions(-) rename src/backend/port/tas/{hpux.s => hpux_hppa.s} (100%) diff --git a/configure b/configure index 4eef19ca94..7f242d4950 100755 --- a/configure +++ b/configure @@ -1453,7 +1453,7 @@ PORTNAME=$template # assembler code in src/include/storage/s_lock.h, so we just use # a dummy file here. case $host in - *-*-hpux*) need_tas=yes;
