graham sanderson 9f68faf5ab Various small fixes towards building with other compilers ... * Fix various non-GCC warnings (no effect on GCC) * Reduce use of typeof since non GCC compilers may not support it * Introduce PICO_C_COMPILER_IS_GNU, PICO_C_COMPILER_IS_CLANG, PICO_C_COMPILER_IS_IAR to CMake as if (CMAKE_C_COMPILER_ID STREQUAL "xxx") is a bit verbose * Use "unified_asm" macro for all inline asm (it is "volatile __asm" on GNU with a .syntex unified) * Use NOLOAD instead of COPY in linker scripts (arguably more correct anyway) * Use the same style for setting _etext in all 4 linker scripts (to the beginning of .data). Clang aligns .data on a 16 byte boundary. Note ideally we'd add a new symbol __data_source, however that would break backwards compatibility with existing user linker scripts * Use "a" for .stack, .heap sections because clang complains otherwise, and they are explicitly NOLOAD anyway * Avoid duplicating __sev, __wfe, __wfi which Clang sometimes seems to provide as built-ins * Add missing kitchen_sink_blocked_ram binary * Allow build with LLVM Embedded Toolchain Form ARM v 14.0.0 (unsupported atm)		2023-02-27 15:38:28 -06:00
