Changes in this Release

Updates to GCC

Updated to GCC 8.3.

For the full list of improvements to optimizations, compiler messages, new options and more, visit https://gcc.gnu.org/gcc-8/

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

Known Limitations

The GDB Agent is not able to connect to MSP430L092 target devices.
The GDB Agent is not able to connect to RF430FRL15xH target devices.
