Date: 27 Mar 2002 00:21:18 -0800 reopen 139003 thanks 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. diff -urN postgresql-7.2/src/backend/storage/lmgr/s_lock.c postgresql-7.2.f= ixed/src/backend/storage/lmgr/s_lock.c --- postgresql-7.2/src/backend/storage/lmgr/s_lock.c Mon Nov 5 18:46:28 20= 01 +++ postgresql-7.2.fixed/src/backend/storage/lmgr/s_lock.c Wed Mar 27 07:46= :59 2002 @@ -173,9 +173,12 @@ .global tas \n\ tas: \n\ .frame $sp, 0, $31 \n\ + .set push \n\ + .set mips2 \n\n ll $14, 0($4) \n\ or $15, $14, 1 \n\ sc $15, 0($4) \n\ + .set pop \n\ beq $15, 0, fail\n\ bne $14, 0, fail\n\ li $2, 0 \n\ --=-Zd+0ZcrpBCpp9VY6uMyv Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQA8oZTcYU1MND4dDBwRAoauAJ4t+mR9gTqOYDdaDKLKytoPj811YwCgz/4k D34xRYM+se1wuNOGGQST3Yo= =Hmbh -----END PGP SIGNATURE----- --=-Zd+0ZcrpBCpp9VY6uMyv--
