From e7d556dfef22edc573b26552828940679ec437ee Mon Sep 17 00:00:00 2001 From: Thiemo Seufer Date: Sun, 26 Aug 2001 10:42:12 +0000 Subject: [PATCH] * tc_mips.h (MAX_GPREL_OFFSET): Change it to the maximum allowed value, not the word beyond maximum. * tc_mips.c (macro_build_lui): Code cleanup. (macro): Reflect change to MAX_GPREL_OFFSET. (mips_ip): Check explicitly against S_EX_NONE. (my_get_SmallExpression): parse for %gp_rel, not %gprel.
