Internal Compiler Error In Save_call_clobbered_regs At Caller-save.c

There is also a danger of calling a function that returns a structure without declaring it as such.

In C, this is represented by the expression *(&name+constant). I queue your proposed patch for 3.3.5. It looks similar to these two bugs that are related to some optimization bug in GCC: * http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45259 (I can't reproduce this one) * https://bugzilla.redhat.com/show_bug.cgi?id=622060 (This was detected in Fedora for Six of the compilers (MIPS 3000, SPARC, Intel 386, Power PC, DEC Alpha, and Motorola 68020) are considered active and are used to compile current versions of Plan 9.

What were the compilation options that triggered it? All of the object-independent parts are combined into source files in the directory /sys/src/cmd/cc. When one ports the compiler, this table is usually initialized so that leaves are labeled as addressable and nothing else. IOW: $ git reset --hard c8010b803d34fa7e096747067e33c650b36ecc06 # build gcc/wine - gcc fails to build wine, internal compiler error $ git show d73df2920c77116fd88e03cd95dd352f16511a3f | patch -p1 # build gcc/wine - wine segfaults

Thus node->dval and node->locked are legitimate references. They are not in the PR. Reopened as 5.0 regression. Such functions will not be profiled when profiling is enabled for the rest of the program.

This saves a copy and makes the compilation much less clumsy. http://gcc.gnu.org/PR14671 reload_completed && flag_unroll_loops) > { > - /* ??? Looking at PR15660, the connection to the patch seems tenuous ( #2 0x080dcc14 in gt_ggc_ma_alias_invariant). Several others (Motorola 68000, Intel 960, ARM 7500, AMD 29000) have had only limited use, such as to program peripherals or experimental devices. 2.

PR14671 fixed a problem where objects in reg_known_value were being poissoned because objects in reg_known_value weren't being marked. See PR56881.

This number is roughly the number of registers required to compile the tree on an ideal machine.

For the most part, this is highly specific to a particular processor. Functions returning structures Structures longer than one word are awkward to implement since they do not fit in registers and must be passed around in memory. Now it ICEs even compiling the library itself: rguenth@alwazn r2 $ g++-3.3 -c /net/bellatrix/home/rguenth/src/pooma-bk/r2/src/IO/DiskLayout.cmpl.cpp -o /net/bellatrix/home/rguenth/src/pooma-bk/r2/src/IO/LINUXgcc33a/DiskLayout.cmpl.o -ftemplate-depth-60 -fno-exceptions -Drestrict=__restrict__ -O2 -funroll-loops -g -I/net/bellatrix/home/rguenth/src/pooma-bk/r2/src -I/net/bellatrix/home/rguenth/src/pooma-bk/r2/lib/LINUXgcc33a -v Reading specs from /net/bellatrix/home/rguenth/ix86/gcc3.3-270504/bin/../lib/gcc-lib/i686-pc-linux-gnu/3.3.4/specs Configured with: I do notice that the logic for error handling was changed from doing a "break" to doing a "goto error". ---------- _______________________________________ Python Related Discussions [issue16109] urllib2.urlopen throws HTTP Error in

As this is GC related, try --param ggc-min-expand=100 --param ggc-min-heapsize=131072, which is what gcc uses for me. Comment 11 Kirill Smirnov 2013-04-23 21:33:10 UTC I'm sorry I cannot reproduce invalid behaviour within a refined test case. Together with Erics (second) proposed patch to PR13653 POOMA | is now regression-free with gcc 3.3! have a peek at these guys git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@187459 138bc75d-0d04-0410-961f-82ee72b054a4 after this commit, wine will fail to build (with default -O2 settings, gcc will crash with an internal error).

See for instructions. Please include the complete backtrace with any bug report. All of the variables that can be potentially registerized within a procedure are placed in a table. (Suitable variables are any automatic or external scalars that do not have their addresses At one end of the spectrum are the 68020 and VAX, which allow a complex mix of incrementing, decrementing, indexing, and relative addressing.

For the MIPS processor, the loader makes a pass over the internal structures, exchanging instructions to try to fill ‘‘delay slots’’ with useful work. I did a new build with the patch below. Szymanski, ‘‘Assembling Code for Machines with Span-dependent Instructions’’, Communications of the ACM, Vol 21(4), pp. 300-308, 1978. This is true for references to structures and to references to pointers to structures.

The code produced is poor, but porting is easy. This changeset triggered the problem: changeset: 79693:ac30a1b1cf17 user: Benjamin Peterson date: Fri Oct 12 11:34:51 2012 -0400 summary: ceval cleanup It's fairly large (http://hg.python.org/cpython/rev/ac30a1b1cf17), so I can't easily tell which RTH seems to have applied a patch to mark > reg_known_value on the 24th. Two problems have come up in retrospect.
