TI has partnered with Mitto Systems Limited to bring you a new and fully supported open source compiler. This free MSP430 GCC compiler has no code size limit.
This compiler can be used as a standalone or can be integrated in Code Composer Studio.
- GCC 126.96.36.199
- GDB 8.1
- binutils 2.26.0
- Newlib 2.4.0
- MSPDebugStack 3.14.0.0000
- MSP430 header and support files 1.208
Changes in this Release
- Updates to GCC
- Updated to GCC 8.3.
- Fixed interrupt functions unnecessarily saving all callee-saved registers when the interrupt function calls another function. (Known Issue MSPGCC-39)
- Added alternate version of "__int20" type, "__int20__".
- __int20__ can be used in code compiled with options that enable ISO C standard checking (e.g. -pedantic), without causing warnings or errors about its use to be emitted.
- Fixed paths specified with -Wl,-L not being searched for the MSP430 MCU data file "devices.csv". (Known Issue MSPGCC-176)
- Fixed msp430-gcc support files sometimes not being found when installed into the "msp430-elf/include/devices/" subdirectory of the toolchain.
- Fixed inclusion of C runtime library functions not being dynamic with LTO. (Known Issue MSPGCC-156)
- Fixed identical interrupt functions being folded using the regular function calling convention. (Known Issue MSPGCC-175)
- Functions marked with the interrupt attribute will not be cloned or folded.
- Enabled register names specified in "asm" statement clobber lists or in command line arguments to be case-insensitive.
- For example, a lower-case "r" in "r4" can be used and GCC will no longer be report the register name as unrecognized.
- Updates to Binutils
- Fixed object attribute for data region overlapping with "OFBA_MSPABI_Tag_enum_size" mspabi attribute.
- Updates to Newlib (C Library)
- Further improvements to dynamic C runtime (CRT) functionality, reducing code size.
- Removed .init and .fini sections. Initialization functions in the .init_array section will be run before mainis called (if this section is populated).
.fini and .fini_array are unused.
- Updates to GDB
- Fixed packet error when flashing large files on some devices by increasing default "remotetimeout" to 10 seconds. (Known Issue MSPGCC-177)
- Updates to MSP430 Header and Support Files
- Added missing ALIGN directives for .preinit/init/fini_array sections in GCC linker command files
- The GDB Agent is not able to connect to MSP430L092 target devices.
- The GDB Agent is not able to connect to RF430FRL15xH target devices.
