From ff19ae595773ba24ee8bdf8d581a573ecf3cba31 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 9 Aug 2001 21:04:29 +0000 Subject: 2001-08-09 Chris Johns * cpu_asm.S: This patch was co-developed with Eric Norum . It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price. --- c/src/exec/score/cpu/m68k/ChangeLog | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'c/src/exec/score/cpu/m68k/ChangeLog') diff --git a/c/src/exec/score/cpu/m68k/ChangeLog b/c/src/exec/score/cpu/m68k/ChangeLog index 3071ea8aa1..8e42f7f373 100644 --- a/c/src/exec/score/cpu/m68k/ChangeLog +++ b/c/src/exec/score/cpu/m68k/ChangeLog @@ -1,3 +1,15 @@ +2001-08-09 Chris Johns + + * cpu_asm.S: This patch was co-developed with Eric Norum + .
