>From Joel Sherrill:
Gcc on the head fails to compile arm-rtems4.7 at the following point
when Ada is enabled.
../../xgcc -B../../ -c -g -O2 -W -Wall -gnatpg s-auxdec.adb -o
s-auxdec.o
s-auxdec.ads:286:13: alignment for "Aligned_Word" must be at least 4
The code is:
type Aligned_Word is record
Value : Short_Integer;
end record;
for Aligned_Word'Alignment use
Integer'Min (2, Standard'Maximum_Alignment);
I (Laurent) think Standard'Maximum_Alignment comes from ada/targtyps.c
get_target_maximum_alignment (void)
{
return BIGGEST_ALIGNMENT / BITS_PER_UNIT;
}
Joel confirmed that changing "Min (2" to "Min (4" enable this file to be
compiled, however my reading of the source would imply that BIGGEST_ALIGNMENT
is at least 32 on arm, so something else must be at play here, any idea?
