This will ensure the + assembler does not select the link register as the temp register as + was occasionally happening previously. + + The assembler statements are now included in a single asm block rather + than each line having its own asm block. + + Changes from V4.5.0 + + Removed the portENTER_SWITCHING_ISR() and portEXIT_SWITCHING_ISR() macros + and replaced them with portYield_FROM_ISR() macro. Application code + should now make use of the portSAVE_CONTEXT() and portRESTORE_CONTEXT() + macros as per the V4.5.1 demo code. */ #ifndef PORTMACRO_H #define PORTMACRO_H /* *INDENT-OFF* */ #ifdef __cplusplus extern "C" { #endif /* *INDENT-ON* */ /*----------------------------------------------------------- * Port specific definitions. * * The settings in this file configure FreeRTOS correctly for the * given hardware and compiler. * * These settings should not be altered. *----------------------------------------------------------- */ #include /* Type definitions. */ #define portCHAR char #define portFLOAT float #define portDOUBLE double #define portLONG long #define portSHORT short #define portSTACK_TYPE uint32_t #define portBASE_TYPE long typedef portSTACK_TYPE StackType_t; typedef long BaseType_t; typedef unsigned long UBaseType_t; #if ( configUSE_16_BIT_TICKS == 1 ) typedef uint16_t TickType_t; #define portMAX_DELAY ( TickType_t ) 0xffff #else typedef uint32_t TickType_t; #define portMAX_DELAY ( TickType_t ) 0xffffffffUL #endif #define portPOINTER_SIZE_TYPE uint64_t /*-----------------------------------------------------------*/ /* Requires definition of UBaseType_t */ #include "fake_port.h" #include /* Hardware specifics. */ #define portTICK_PERIOD_MS ( ( TickType_t ) 1000 / configTICK_RATE_HZ ) #define portBYTE_ALIGNMENT 8 #define portNOP() __asm volatile ( "NOP" ) /* * These define the timer to use for generating the tick interrupt. * They are put in this file so they can be shared between "port.c" * and "portisr.c". */ #define portTIMER_REG_BASE_PTR #define portTIMER_CLK_ENABLE_BIT #define portTIMER_AIC_CHANNEL /*-----------------------------------------------------------*/ /* Task utilities. */ /* * portRESTORE_CONTEXT, portRESTORE_CONTEXT, portENTER_SWITCHING_ISR * and portEXIT_SWITCHING_ISR can only be called from ARM mode, but * are included here for efficiency.
