Internal Compiler Error In Save_call_clobbered_regs At Caller-save.c

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

Comment 28 Uroš Bizjak 2014-10-03 18:10:41 UTC (In reply to Jakub Jelinek from comment #27) > Shouldn't it be guarded by if (ksvd.ignored_set_reg) too? External register The declaration extern register will dedicate a register to a variable on a global basis. Comment 15 Jakub Jelinek 2013-04-24 16:50:21 UTC Ah, ok, I can see it. The CALL_INSN pattern has clobbers for rsi/rdi, but copyprop_hardreg_forward_1 processes those early, perhaps then the CALL_INSN_FUNCTION_USAGE changes something and relies on regs_invalidated_by_call processing to invalidate whatever is necessary.

  1. A quick search on http://gcc.gnu.org/bugzilla/ doesn't show anything for that commit.
  2. Registerization Up to now, the compiler has operated on syntax trees that are roughly equivalent to the original source language.
  3. Yes, but I will need Mark's approval.
  4. Since the stack grows down in Plan 9, the Plan 9 compilers keep neither an explicit frame pointer nor an explicit argument pointer; instead they generate addresses relative to the stack
  5. If all of the data cannot fit into the first 64K of the data segment, then usually only a few large arrays need more expensive addressing modes.

In this pass, the leaves are labeled with small integers. The execution time does not significantly depend on library implementation. For example:     enum    errors     {         Etoobig,         Ealarm,         Egreg     };     char* errstrings[] =     {         [Ealarm]    "Alarm call",         [Egreg] "Panic: out of mbufs",         [Etoobig]   "Arg list too long",     }; In the same way, individual structures members may be initialized in any order by preceding the initialization Thanks.

I didn't take benchmarks but we can do that anytime during the F15 cycle by running benchmarks, turning off computed-goto, rerunning benchmarks. Finally, in places where context is insufficient to identify the unnamed structure, the type name (it must be a typedef) of the unnamed structure can be used as an identifier.

It is not triggered by a recent patch. What I did was put a watch on "reg_known_value[294]->code != PLUS" after the array location had been initialized in init_alias_analysis. W.

Object files and libraries are combined by a loader program to produce the executable binary. There are other departures from the standard, particularly in the libraries, that are beyond the scope of this paper. 3.1. The Language The compiler implements ANSI C with some restrictions and extensions [ANSI90]. I think they deserve some consideration because they are _serious_ IMHO.

Unnamed substructures The most important and most heavily used of the extensions is the declaration of an unnamed substructure or subunion. More debugging needs to be done to find more about "p" and what's really the problem in marking this object. Unfortunately, all compilations must be complete before loading can begin. Of course the patch may just uncover a latent problem - but that still makes rth (or the backporter) responsible of fixing the fallout.

I've verified that the patch from http://bugs.python.org/issue6603 has been applied in the tarball we're using. I studied this problem further today. The loader The loader is a multiple pass program that reads object files and libraries and produces an executable binary. Looking at PR15660, the connection to the patch seems tenuous ( #2 0x080dcc14 in gt_ggc_ma_alias_invariant).

On a shared-memory multi-processor, an external register is one-per-processor and neither one-per-procedure (automatic) or one-per-system (external). With ANSI C function prototypes, this error need never occur. 5.
