Re: error: unable to find a register to spill in class 'FP_REGS'

ger reg, then 8 insns would need reloads. Ok that's clear. Thanks for explaining. Nevertheless I can't figure out from the above files what's wrong and maybe I am just lacking of the right interpretation of these intermediate files. Can you figure out any abnormal behaviour from the above file excerpts? Thanks in advance, Markus Franke

error: unable to find a register to spill in class 'FP_REGS'

HARD_REGNO_MODE_OK (regno, rl->mode)) ---snap--- This causes in the end the error message because no suitable registers could be found. Does anybody have an idea what could be wrong in the machine description or to where start finding the error? Any suggestions are welcome. Regards, Markus Franke -- Nichts ist so praktisch wie eine gute Theorie!

call_value pattern

sage. ---snip--- int odd(int i) { return i & 0x1; } int foo(int i, int j) { int a; a=odd(i+j); return a; } ---snap--- If simply omit the "a=odd(i+j)"-line everything works fine so it has something to do with this call. What am I doing wrong? It seems so simple but I can't figure out what's wrong with my pattern. Regards, Markus Franke

Hello, thank you for your answer. Having changed the code in the way you suggested I get still the same warning message. Any further suggestions? Regards, Markus Ian Lance Taylor wrote: > Markus Franke <[EMAIL PROTECTED]> writes: > > >>---snip--- >>;; >&

al\\t%S0%(" [(set_attr "type" "jump") (set_attr "mode" "none")]) ---snap--- I think the warning is caused by the second parameter of the set instruction, right? But I don't know where to specify the source mode. I had already a look into the GCC Internals Manual without success. Any suggestions how to fix this problem? Regards, Markus Franke

Thank you very much. That was exactly the information I was looking for. I will think about a contribution to the GCC Internals. Thanks again, Markus Franke Rask Ingemann Lambertsen wrote: > On Tue, Jan 16, 2007 at 11:24:56AM +0100, Markus Franke wrote: > > >>I am wondering wher

Thank you for your response. I understood everything you said but I am still confused about the file -protos.h. Which prototypes have to be defined there? Thanks in advance, Markus Franke pranav bhandarkar wrote: >> I am wondering where to define the prototypes for functions in >>

standardised code in order to contribute my development. I would appreciate any help. By the way, I already had a look in the GCC Internals manual but I am still a bit confused. Thanks in advance and regards, Markus Franke

needed headerfiles in .c

me kind of standard set of Header-Files exists which is needed by every backend? Can somebody give me a list or something like that. I had already a look at the Internals Manual but without finding something about it. Thanks in advance, Markus Franke

poisened macro definitions

PAREN" "ASM_GLOBALIZE_LABEL" "FUNCTION_ARG_PARTIAL_NREGS" --snap--- I read something about poisened macros and that they shouldn't be used anymore. But in fact I was not able to find any documentation about these macros. When were they declared as poisened and especially why? What should be done instead of using this macros? Just uncommenting everything can't be a solution. I was also looking in GCC-Internals manual without any success. Thanks for your help, Markus Franke

machine-dependent Passes on GIMPLE/SSA Tree's?
