>Description:
I was trying to generate a minimum ada runtime library for the avr (e.g. at90s8535) by copying the required *.ads and *.adb files to <prefix>/lib/gcc-lib/avr/3.4/ada-include and compile them.
What I got was a number of ICEs of the form:
+===========================GNAT BUG DETECTED==============================+
| 3.4 20030509 (experimental) (avr-unknown-none) Gigi abort, Code=305 |
| No source file position information available |
| Please submit a bug report; see http://gcc.gnu.org/bugs.html. |
| Include the entire contents of this bug box in the report. |
| Include the exact gcc or gnatmake command that you entered. |
| Also include sources listed below in gnatchop format |
| (concatenated together with no headers between files). |
+==========================================================================+
The files which generated errors were:
s-stalib.adb, s-parame.adb, i-c.adb, s-maccod.ads
I ran the compilation with
avr-gcc -c -gnatg <filename>
flags -O and -mmcu=at90s8535 didn't make any difference
In file s-maccod.ads the reason for the ICE was the line:
pragma Import (Intrinsic, Asm);
In file i-c.ads the reason for the crash is the definition of type long:
type long is range -(2 ** (System.Parameters.long_bits - 1))
.. +(2 ** (System.Parameters.long_bits - 1)) - 1;
