From f16c3d4f137ae02fab0982782b2e1c2b2afc8583 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Mon, 24 Aug 2020 13:21:31 +0930 Subject: [PATCH] Remove "memory exhausted" messages Since we use xcalloc to set up hash table memory, htab_create won't ever return a failure. * config/tc-aarch64.c (md_begin): Don't bother checking for out of memory failure from str_htab_create. * config/tc-arc.c (arc_insert_opcode, md_begin): Likewise. (arc_extcorereg, arc_stralloc): Likewise. * config/tc-arm.c (md_begin): Likewise. * config/tc-cr16.c (initialise_reg_hash_table, md_begin): Likewise. * config/tc-cris.c (md_begin): Likewise. * config/tc-crx.c (md_begin): Likewise. * config/tc-pdp11.c (md_begin): Likewise. * config/tc-score.c (s3_build_reg_hsh, s3_begin): Likewise. * config/tc-score7.c (s7_build_reg_hsh, s7_begin): Likewise. --- gas/ChangeLog | 14 ++++++++++++++ gas/config/tc-aarch64.c | 31 +++++++++++++++---------------- gas/config/tc-arc.c | 15 --------------- gas/config/tc-arm.c | 19 +++++++++---------- gas/config/tc-cr16.c | 5 +---- gas/config/tc-cris.c | 2 -- gas/config/tc-crx.c | 11 +++-------- gas/config/tc-pdp11.c | 2 -- gas/config/tc-score.c | 15 ++++----------- gas/config/tc-score7.c | 15 ++++----------- 10 files changed, 50 insertions(+), 79 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 75cf73e749..6b634a0f36 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,17 @@ +2020-08-24 Alan Modra + + * config/tc-aarch64.c (md_begin): Don't bother checking for + out of memory failure from str_htab_create. + * config/tc-arc.c (arc_insert_opcode, md_begin): Likewise. + (arc_extcorereg, arc_stralloc): Likewise. + * config/tc-arm.c (md_begin): Likewise. + * config/tc-cr16.c (initialise_reg_hash_table, md_begin): Likewise. + * config/tc-cris.c (md_begin): Likewise. + * config/tc-crx.c (md_begin): Likewise. + * config/tc-pdp11.c (md_begin): Likewise. + * config/tc-score.c (s3_build_reg_hsh, s3_begin): Likewise. + * config/tc-score7.c (s7_build_reg_hsh, s7_begin): Likewise. + 2020-08-24 Alan Modra * config/tc-arm.c (move_or_literal_pool): Avoid false positive diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index 238792758d..db5edcb3dc 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -8686,22 +8686,21 @@ md_begin (void) unsigned mach;
