From: rtel Date: Wed, 18 Jan 2017 18:33:48 +0000 (+0000) Subject: Correct alignment issue in GCC and RVDS Cortex-A9 port that was preventing full float... X-Git-Tag: V10.0.0~40 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=001f5cd5d6f14dcbfe05043ed214c2034b8e7bee;p=freertos Correct alignment issue in GCC and RVDS Cortex-A9 port that was preventing full floating point usage in interrupts (other ports will be updated likewise). Update the Zynq demo to test the GCC Cortex-A9 port layer modification mentioned on the line above. git-svn-id: https://svn.code.sf.net/p/freertos/code/trunk@2479 1d2547de-c912-0410-9cb9-b8ca96c0e9e2 --- diff --git a/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/.cproject b/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/.cproject index 19e0ca50a..bbb71d801 100644 --- a/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/.cproject +++ b/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/.cproject @@ -83,6 +83,9 @@ + + + diff --git a/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/src/Full_Demo/IntQueueTimer.c b/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/src/Full_Demo/IntQueueTimer.c index c86424a72..f6d9aba0f 100644 --- a/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/src/Full_Demo/IntQueueTimer.c +++ b/FreeRTOS/Demo/CORTEX_A9_Zynq_ZC702/RTOSDemo/src/Full_Demo/IntQueueTimer.c @@ -224,6 +224,12 @@ uint32_t ulInterruptStatus; XTtcPs *pxTimer = ( XTtcPs * ) pvCallBackRef; BaseType_t xYieldRequired; +#if( configASSERT_DEFINED == 1 ) + /* Test floating point access within nested interrupts. */ + volatile long double d1, d2; +#endif + + /* Read the interrupt status, then write it back to clear the interrupt. */ ulInterruptStatus = XTtcPs_GetInterruptStatus( pxTimer ); XTtcPs_ClearInterruptStatus( pxTimer, ulInterruptStatus ); @@ -234,11 +240,37 @@ BaseType_t xYieldRequired; /* Check the device ID to know which IntQueue demo to call. */ if( pxTimer->Config.DeviceId == xDeviceIDs[ 0 ] ) { + #if( configASSERT_DEFINED == 1 ) + { + /* Test floating point access within nested interrupts. */ + d1 = 1.5L; + d2 = 5.25L; + } + #endif /* configASSERT_DEFINED */ + xYieldRequired = xFirstTimerHandler(); + + /* Will fail eventually if flop context switch is not correct in + interrupts.
