Hello,
these are bugs in the gcc toolchain's include files.
I searched through all header files of Atmel Studio 6.0's 8 bit gcc include files, Version:
AVRGCC - 3.4.0.65
AVR Toolchain 8 Bit
Version: 3.4.0.663 - GCC 4.6.2
I used this RegEx (regular expression) pattern...
[\w]__[\w]
...to find all macro names that contain a double underscores (__) that are not at the beginning or end of a macro name.
I found there are many misspelled defines, this may eventually regard interrupt vectors only, that contain two underscores (__) in their name where just one (_) belongs.
For the MCUs I use, I created this nasty and of course very limited work-around that fixes the spelling for a few macro names:
Code:
/* Work-Around for a bug in the Atmel gcc toolchain
Installed Packages: AVRGCC - 3.4.0.65
AVR Toolchain 8 Bit
Version: 3.4.0.663 - GCC 4.6.2
ATMega164PA + ATMega324A + ATMega324P : several defines have a double underscore (__)
so these defines are just bugfixes:
*/
#if ( defined (__AVR_ATmega164PA__) || (__AVR_ATmega324A__) || defined (__AVR_ATmega324P__) )
#ifndef SPI_STC_vect
#define SPI_STC_vect SPI__STC_vect
#endif
#ifndef USART0_RX_vect
#define USART0_RX_vect USART0__RX_vect
#endif
#ifndef USART0_UDRE_vect
#define USART0_UDRE_vect USART0__UDRE_vect
#endif
#ifndef USART0_TX_vect
#define USART0_TX_vect USART0__TX_vect
#endif
#endif
This is the output from the RegEx search:
I assume Atmel has to fix at least one macro name in each of these files:
AVRGCC\3.4.0.65\AVRToolchain\avr\include\avr\io90pwm161.h

Previously reported in the internal tracker as issue DEVXML-306 - hopefully this will be fixed soon by the device header team.

You're giving away interesting tidbits of the Atmel Norway organization, Dean.  A team for device headers?!?
What will be revealed next? A division for the RESET pin of the ATmega88?  |

For what it's worth, some teams are subsets of other teams, not dedicated employees. The header team is most likely a subset of the toolchain team, but I haven't looked into it.
I can't talk about the /RESET line team, that's a company secret.

Probably Human Resources.  |

| Hmm. Given that I generally don't know what I'm doing anyhow, that would be really confusing! Glad I haven't tried to use one of those yet. |
