Release Information

TI has partnered with Red Hat 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.
The MSP430-GCC 4.0.1.0 standalone package based on GCC compiler to 5.3.0 (msp430-15r1-105) will be the last release as maintained by Red Hat.
For future releases, Texas Instruments will be partnering with SOMNIUM Technologies for maintenance of the MSP430 GCC compiler.

Changes in This Release

Updated GCC compiler to 5.3.0 (msp430-15r1-105)
Mac OS X production release
Updated support files to version 1.188
Replaced macro in iomacros.h:
#define __interrupt(vec) __attribute__((__interrupt__(vec)))
with
#define __interrupt __attribute__((__interrupt__)) #define __interrupt_vec(vec) __attribute__((interrupt(vec)))
Impact: Old #define __interrupt(vec) __attribute__((__interrupt__(vec))) removed.
Please update your macro by the new one: change __interrupt(vec) by __interrupt_vec(vec)
Components version

GCC 5.3.0
GDB 7.7
binutils 2.25
Newlib 2.2.0
MSPDebugStack 3.7.0.12
MSP430 GDB Agent 6.0.14.5

Updated GCC compiler to 5.3.0 (buildid 105)

5.3.0 patches applied
RRA/RLA performance tweak:
https://e2e.ti.com/support/development_tools/compiler/f/343/t/481737
New version.properties file in root directory with version=5.3.0.105 vendor=Red Hat
Includes latest -mmcu devices list with hw mpy and ISA settings.

If the -mmcu device is unknown then compiler chooses sw mpy and emits warning for user to set manually

GCC compiler 5.2.1 (buidlid 50) changes vs. GCC compiler to 4.9.1 (buildid 364)

Library size reduced by pulling out hw mpy routines to their own library
Silicon errata updates:

-msilicon-errata-warn= Passes on a request to the assembler to warn about various silicon errata
-msilicon-errata= Passes on a request to the assembler to enable fixes for various silicon errata
CPU8/CPU11/CPU13: added assembler warning
CPU19: updated to add NOP after write to CPUOFF if following instruction has an indirect addressed operand. Also added assembler warning.

Support added for new variable attribute "persistent" which allows for initializing once during load and then never again during resets/restarts.
Invalid startup code for disabling watchdog in msp430/crt0.S was removed.
Key Changes to Header & Support Files

.persistent section added to linker script
New file for symbol definitions is added for every device
new macros added to iomacro.h

#define sfr_b(x) extern volatile unsigned char x

#define sfr_w(x) extern volatile unsigned int x

#define sfr_a(x) extern volatile unsigned long int x

#define sfr_l(x) extern volatile unsigned long int x

heap memory support added to linker scripts

Revised TAG_ADC10_1 values for applicable devices
Added upper bss section in GCC linker files
Removed invalid LCD definitions in CC430F514x header and support files
Added CAPTIVATE registers
Added mhwmult option in the GNU Compiler option with the CCS device.xml files
Fixed AESOP_2 and AESOP_3 comments mismatch and typo
