From 94dd4f6cdfa1d1aba18f8259ebb10ea52a344322 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 17 Feb 2009 20:39:44 +0000 Subject: 2009-02-17 Joel Sherrill * rtems/score/sh.h: SH2E and SH3E have a DSP rather than an FPU. They are not compatible. We currently only support the FPU found on the SH3 and SH4. --- cpukit/score/cpu/sh/rtems/score/sh.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'cpukit/score/cpu/sh/rtems/score/sh.h') diff --git a/cpukit/score/cpu/sh/rtems/score/sh.h b/cpukit/score/cpu/sh/rtems/score/sh.h index b19855abe1..32b7d6b05a 100644 --- a/cpukit/score/cpu/sh/rtems/score/sh.h +++ b/cpukit/score/cpu/sh/rtems/score/sh.h @@ -46,8 +46,12 @@ extern "C" { * predefines. */ -#if defined(__SH2E__) || defined(__SH3E__) || \ - defined(__SH4__) || defined(__SH4_SINGLE_ONLY__) +#if defined(__SH2E__) || defined(__SH3E__) + +/* FIXME: SH-DSP context not currently supported */ +#define SH_HAS_FPU 0 + +#elif defined(__SH4__) || defined(__SH4_SINGLE_ONLY__) /* * Define this if you want to use XD-registers. -- cgit v1.2.3
