* Pass top of stack to configINIT_TLS_BLOCK Picolibc wants to allocate the per-task TLS block within the stack segment, so it will need to modify the top of stack value. Pass the pxTopOfStack variable to make this explicit. Signed-off-by: Keith Packard <keithpac@amazon.com> * Move newlib-specific definitions to separate file This reduces the clutter in FreeRTOS.h caused by having newlib-specific macros present there. Signed-off-by: Keith Packard <keithpac@amazon.com> * Make TLS code depend only on configUSE_C_RUNTIME_TLS_SUPPORT Remove reference to configUSE_NEWLIB_REENTRANT as that only works when using newlib. configUSE_C_RUNTIME_TLS_SUPPORT is always set when configUSE_NEWLIB_REENTRANT is set, so using both was redundant in that case. Signed-off-by: Keith Packard <keithpac@amazon.com> * portable-ARC: Adapt ARC support to use generalized TLS support With generalized thread local storage (TLS) support present in the core, the two ARC ports need to have the changes to the TCB mirrored to them. Signed-off-by: Keith Packard <keithpac@amazon.com> * Add Thread Local Storage (TLS) support using Picolibc functions This patch provides definitions of the general TLS support macros in terms of the Picolibc TLS support functions. Picolibc is normally configured to use TLS internally for all variables that are intended to be task-local, so these changes are necessary for picolibc to work correctly with FreeRTOS. The picolibc helper functions rely on elements within the linker script to arrange the TLS data in memory and define some symbols. Applications wanting to use this mechanism will need changes in their linker script when migrating to picolibc.

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
