[Bug target/52488] avr-*: internal compiler error: in extract_insn, at recog.c:2123
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52488 --- Comment #9 from Ralf Corsepius ralf_corsepius at rtems dot org 2012-03-13 06:16:03 UTC --- (In reply to comment #8) (In reply to comment #7) You can look up in the device datasheet to see how much RAM it has. Well, datasheets is one thing, GCC's internal notion is yet another. Or do you want GCC to print out how much RAM each device has? No, I would expect GCC to print its rationale for this rejection. e.g. something like allocating 2050 byte of stack exceeds maximum stack size (1024 bytes) ... Well, my view is different: The avr's default set of multilib variants is non-suitable as general default set of multlib variants. It probably is suiteable as set of multilibs for bare-metal targets, but does not meet the demands of OSes. Do you have recommendations? Or better still, a patch? We will see, I am currently looking into implementing custom multilibs for avr-RTEMS, which may result into a patch addressing this as a side-effect. However, the avr's multilib implementation diverges from what is used almost elsewhere in GCC to an extend, this is a tedious.

At this point it cannot be said if this PR is really the same as PR50925, but it's not unlikely. I am confused: PR50925 says fails to build 4.6.2, however avr-rtems-gcc4.6.2 and 4.6.3 are known to build, c.f. (4.6.2-based rpms) ftp://ftp.rtems.org/pub/rtems/linux/obsolete/4.11/fedora/16/ and (4.6.3-based rpms) ftp://ftp.rtems.org/pub/rtems/linux/4.11/fedora/16 ... but 4.7.0 does not BUILD at all! = Regression

However, this warning still leaves users in unclearity as GCC doesn't tell the maximum of stack it can provide. (In reply to comment #6) avr-gcc 4.7 implements PR51345 which result in new multilib variants for tiny devices with only 8-bit SP. newlib derives its build configury from -print-multi-directory Yes, that's the way multilibs are being built ever since multilibs exists ( 20 years?). or whatever and tries to build insane code with 2050 bytes of stack for device(s) with only 128 bytes of RAM. Well, my view is different: The avr's default set of multilib variants is non-suitable as general default set of multlib variants. It probably is suiteable as set of multilibs for bare-metal targets, but does not meet the demands of OSes. That said, I feel RTEMS needs to implement custom multilibs for the avr.

[Bug target/31797] New: powerpc: race
When building RTEMS with gcc-4.2.0-20070430, gcc races on one file of the RTEMS sources. It consumes up all available CPU time, gradually (very slowly) seems consume all memory and doesn't seem to finish: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 6176 joel 18 0 1614m 937m 604 D2 92.9 491:53.20 cc1 # ps ax | grep cc1 6176 ?D491:55 /opt/rtems-4.8/libexec/gcc/powerpc-rtems4.8/4.2.0/cc1 -quiet -imultilib m7400 -isystem ../../../../../.././mvme5500/lib/include -MD network_rel-GT64260eth.d -MF .deps/network_rel-GT64260eth.Tpo -MP -MT network_rel-GT64260eth.o -MQ network_rel-GT64260eth.o -DHAVE_CONFIG_H -D_KERNEL -Dmpc7455 -isystem ../../../../../.././mvme5500/lib/include ../../../../../../../../current/c/src/lib/libbsp/powerpc/mvme5500/network/GT64260eth.c -quiet -dumpbase GT64260eth.c -mcpu=7450 -mno-altivec -mabi=altivec -mvrsave=no -mmultiple -mstring -mstrict-align -ansi -auxbase-strip network_rel-GT64260eth.o -g -O2 -Wall -ansi -fasm -o - This issue is reproduceable on i386-FC5 and FC6.

This is the minimised *.c having been extracted from newlib's file exposing the
bug:
-- snip --
extern void (*array_start []) (void);
extern void (*array_end []) (void);
void
init_array (void)
{
int count;
int i;
count = array_end - array_start;
for (i = 0; i count; i++)
array_start[i] ();
}
-- snip --
Pretty trivial code, isn't it?

I noticed it for the first time shortly before submitting this PR (Opened: 2004-03-17; cf. above;). I don't recall the corresponding gcc-release off hand but notes in my build-scripts indicate this bug to have appeared before gcc-3.4.0. As gcj doesn't build for most of my usual targets (embedded *rtems cross-toolchiains) due to lack of the infrastructure it requires, I have disabled building gcj since then and can't tell if this issue has re-appeared or if had been persistent since then. I can't speak for the original reporter of this bug though. I am the original reporter ;) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14614

The PR is against 3.4-branch, because this is what I am using, what I tested the patch with and what I am reporting the bug against. 2. The patch applies to HEAD without changes. 3. Why is GCC asking to file PRs to bugzilla, if they are requested to post patch proposals to gcc-patches afterwards.

--- Additional Comments From ralf_corsepius at rtems dot org 2004-10-04 13:22 --- 1. I am used to my patches being ignored :( Therefore I usually attach them to a PR they are trying to solve to prevent them from being ignored. 2. Note that http://gcc.gnu.org/contribute.html doesn't even mention gcc-patches@ 3. I would expect PRs in bugzilla to become assigned to somebody (maintainer) who will take care about it and process it. Anyway, I'll once again, duplicate this PR and try to send it to gcc-patches@, if I should I manage to convince gcc-patches@'s broken spam filter to let me send.
