Hi,
I just found out myself last night ;-).
Also I just posted a patch I wrote. Currently I'm running my own branch () at
https://c0de.pw/bg/binutils-gdb .
I just tested the binary version of as for ARM I have and it again produces the
unexpected behavior. It Identifies itself as "GNU assembler (2.25-5+5+b1)
2.25".
I use the following command:
> arm-none-eabi-as -o arm-test.o test.S
I just saw that MSP430 is affected in the same way as AVR.
On my current target list are the following microcontroller architectures:
* avr (ATmega128)
* arm (Cortex-M3)
* msp430
I completely agree, that this is a per target issue. But for the named targets
I see no reason for this padding. I currently also do not understand why
padding of the section depends on an alignment specified to align data
structures.
Thanks :-)
(btw. good work!)
