From 3cbe6b2478d7a321e203857f255bcaf69bcc5c8d Mon Sep 17 00:00:00 2001 From: Bruce Momjian Date: Fri, 5 Apr 2002 11:38:13 +0000 Subject: [PATCH] Looks like a small patch is needed as well to do the right thing on Linux. The patch enables the mips2 ISA for the ll/sc operations, and then restores it when done. The kernel/libc emulation code will take over on CPUs without ll/sc, and on CPUs with it, it'll use the operations provided by the CPU. Combined with the earlier fix (removing -mips2), postgresql builds again on mips and mipsel. The patch is against 7.2-7.
