|
* Changes from V3.2.3
|
|
*
|
|
+ Modified portENTER_SWITCHING_ISR() to allow use with GCC V4.0.1.
|
|
+
|
|
+ Changes from V3.2.4
|
|
+
|
|
+ Removed the use of the %0 parameter within the assembler macros and
|
|
+ replaced them with hard coded registers. 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.
