From 874d7e6ef9c750b3e7bccd1dda98ada93f6554eb Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 21 Sep 2016 16:49:15 +0100 Subject: [PATCH] [AArch64][SVE 10/32] Move range check out of parse_aarch64_imm_float Since some SVE constants are no longer explicitly tied to the 8-bit FP immediate format, it seems better to move the range checks out of parse_aarch64_imm_float and into the callers. gas/ * config/tc-aarch64.c (parse_aarch64_imm_float): Remove range check. (parse_operands): Check the range of 8-bit FP immediates here instead. --- gas/ChangeLog | 5 +++++ gas/config/tc-aarch64.c | 14 ++++++-------- 2 files changed, 11 insertions(+), 8 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 70f0e718415..28b12b4323a 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,8 @@ +2016-09-21 Richard Sandiford + + * config/tc-aarch64.c (parse_aarch64_imm_float): Remove range check. + (parse_operands): Check the range of 8-bit FP immediates here instead. + 2016-09-21 Richard Sandiford * config/tc-aarch64.c (parse_aarch64_imm_float): Report a specific diff --git a/gas/config/tc-aarch64.c b/gas/config/tc-aarch64.c index 388c4bfa20f..2489d5bc1d2 100644 --- a/gas/config/tc-aarch64.c +++ b/gas/config/tc-aarch64.c @@ -2148,7 +2148,8 @@ can_convert_double_to_float (uint64_t imm, uint32_t *fpword) hexadecimal representation is involved).
