From 513f04711d46c1277b9aae4e296ac36b15ec5d7b Mon Sep 17 00:00:00 2001 From: Jeff Law Date: Sun, 7 Nov 1993 20:33:18 +0000 Subject: * First cut at cleaning up PA instruction parsing. * config/tc-hppa.c (pa_get_absolute_expression): Accept pointer to insn structure as an argument, and a pointer to a string. All callers changed. Always read any field selector here. Call evaluate absolute to get a return value. (evaluate_absolute): Addept pointer to insn structure as its argument. All callers changed. (INSERT_FIELD_AND_CONTINUE): New macro for inserting a bitfield into an instruction and continuing the main pa_ip loop. (CHECK_FIELD): New macro for simple range checking of fields. (pa_ip): Delete unused variables. Use INSERT_FIELD_AND_CONTINUE and CHECK_FIELD. All immediate fields now pass through pa_get_absolute_expression which will also handle field selectors. Delete dead code. Simplify. (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are applied are in range. Use bfd_put_32 rather than inserting each byte of the fixed instrution into the buffer ourselves. --- gas/ChangeLog | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'gas') diff --git a/gas/ChangeLog b/gas/ChangeLog index d5da309..5f3afd4 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,5 +1,23 @@ Sun Nov 7 01:02:08 1993 Jeffrey A.
