IIRC Microchip's 8-bit PIC line had poor/nonexistent GCC support because their terrible instruction set provided no way to maintain a data stack. Their own compiler just allocated everything statically.
Granted, it's (thankfully) been over a decade since I had to use a Microchip microcontroller, and they've presumably improved since. But Atmel got it right from the start. GCC-AVR produced beautiful assembly and their ISA was a joy to use. RIP Atmel.
