Gaurav-Aggarwal-AWS 95669cc1a1 Generalize Thread Local Storage (TLS) support (#540) ... * Generalize Thread Local Storage (TLS) support FreeRTOS's Thread Local Storage (TLS) support used variables and functions from newlib, thereby making the TLS support specific to newlib. This commit generalizes the TLS support so that it can be used with other c-runtime libraries also. The default behavior for newlib support is still kept same for backward compatibility. The application writer would need to set configUSE_C_RUNTIME_TLS_SUPPORT to 1 in their FreeRTOSConfig.h and define the following macros to support TLS for a c-runtime library: 1. configTLS_BLOCK_TYPE - Type used to define the TLS block in TCB. 2. configINIT_TLS_BLOCK( xTLSBlock ) - Allocate and initialize memory block for the task's TLS Block. 3. configSET_TLS_BLOCK( xTLSBlock ) - Switch C-Runtime's TLS Block to point to xTLSBlock. 4. configDEINIT_TLS_BLOCK( xTLSBlock ) - Free up the memory allocated for the task's TLS Block. The following is an example to support TLS for picolibc: #define configUSE_C_RUNTIME_TLS_SUPPORT 1 #define configTLS_BLOCK_TYPE void* #define configINIT_TLS_BLOCK( xTLSBlock ) _init_tls( xTLSBlock ) #define configSET_TLS_BLOCK( xTLSBlock ) _set_tls( xTLSBlock ) #define configDEINIT_TLS_BLOCK( xTLSBlock ) Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com>		3 years ago
