Internal Compiler Error In Memory Address At Explow.c

Customers may benefit from the opportunity to use this Beta release; a list of fixed issues is presented below. This patch adds ix86_copy_addr_to_reg to first copy DImode address into a DImode register and then to generate SImode SUBREG in this case. Just switch arms of the if clause. Leonards-on-Sea, E. have a peek at these guys

GCC 4.7 only implements -maddress-mode=long equivalent. This change is only a refinement of another one. Tested only in LP64 mode though. It's not totally wrong, given the context of convert_memory_address_addr_space which is already optimistically correct only. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47564

I believe it is correct for GCC to use 32-bit registers instead of 64-bit registers when displacement is negative.

Why is RN2903 dropping packets - only around 1 in 8 packets is getting through LoRaWAN looks great, but I don't want to pay a subscription. Since x32 runs in 64-bit mode, for address -0x40000300(%rax), hardware sign-extends displacement from 32-bits to 64-bits and adds it to %rax. If the target legitmize_address made a change but didn't give us back something useful, then this routine could ICE in the way you described. https://bugzilla.redhat.com/show_bug.cgi?id=515672 init_set_costs can be saved into target_cfgloop structure), and initializations that only matter from expand_gimple_cfg entry till free_after_compilation (there we could remember the last TARGET_OPTION_NODE (or global) and if current TARGET_OPTION_NODE (or

For 4.7 I'd say we want to split this reinitialization up, into reinitializations that matter for tree optimizations (ideally those could be saved into (and restored from) some save area pointed http://marc.info/?l=gcc-bugs&m=129653213620304 Yes, it is also needed for 4.8. I have noticed that clang doesn't support a similar flag to control code generation, so maybe the gcc created this flag long time ago and now it's just not worth it Some innocent-looking programs are known to cause GCC to gobble preposterous amounts of memory, which could cause it to crash or abort after printing "Virtual memory exhausted".

your example here does not seem to be either of those cases, so if it's still happening with gcc-5.3 & current gcc-6 snapshots, it would be great if you could file http://mttags.com/internal-compiler/internal-compiler-error.php Warning, it may not be ready for prime time...

Jeff Comment 3 Jakub Jelinek 2011-02-01 08:20:20 UTC target attribute is a never ending source of problems.

A possible cause for the "Abort!" message is that the TMPDIR environment variable points to a non-writable directory. dyn->d_tag is signed type and Pmode > > != ptr_mode here. > > Possibly, you must be extra careful with these kinds of awkward setups. You can verify it yourself. Note that these changes were properly not the right ways to fix the code.
