From 1b68deb5993b35cb830dd32b75e91b3766002c4a Mon Sep 17 00:00:00 2001 From: Jackie Smith Cashion Date: Wed, 4 Sep 1996 13:15:28 +0000 Subject: [PATCH] Wed Sep 4 11:24:29 1996 James G. Smith * config/tc-mips.c (load_register): Remove unnecessary code that was causing the high 32bits of 64bit constants to be lost. Fixes PR10503. The compiler was producing the assembler code: dli $3,0xfffffffffffff when constructing the softfloat library. Unfortunately it was being incorrectly assembled. --- gas/ChangeLog | 12 ++++++++ gas/config/tc-mips.c | 13 --------- gas/testsuite/ChangeLog | 11 ++++++++ gas/testsuite/gas/mips/.Sanitize | 2 ++ gas/testsuite/gas/mips/dli.d | 48 ++++++++++++++++++++++++++++++++ gas/testsuite/gas/mips/dli.s | 19 +++++++++++++ 6 files changed, 92 insertions(+), 13 deletions(-) create mode 100644 gas/testsuite/gas/mips/dli.d create mode 100644 gas/testsuite/gas/mips/dli.s diff --git a/gas/ChangeLog b/gas/ChangeLog index d1150b0c620..d83345d8308 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,15 @@ +Wed Sep 4 11:24:29 1996 James G.
