I downloaded the daily source an wanted to build a crosscompiler for
arm with:
make clean buildbase installbase CROSSINSTALL=1 CROSSOPT="-XParm-elf-"
OS_TARGET=embedded CPU_TARGET=arm SUBARCH=armv7m
Starting with what compiler?
2.6.0
I changed the code somehow so that the compiler can continue the compiling.
Now it seems the linker shows errormessages.

I just checked it out again. It looks like there's bad bug in the
compiler regarding large set handling. When inserting this on line 473
debugmsg(booltostr(taicpu(p).opcode in
[A_ADC,A_ADD,A_BIC,A_SUB,A_MUL,A_MVN,A_MOV,A_ORR,A_EOR,A_AND,A_RSB,A_RSC,A_SBC,A_MLA],
true)+' '+booltostr(MatchInstruction(p,
[A_ADC,A_ADD,A_BIC,A_SUB,A_MUL,A_MVN,A_MOV,A_ORR,A_EOR,A_AND,A_RSB,A_RSC,A_SBC,A_MLA],
[C_None], [PF_None]), true), p);
The first condition is false for uxth but for the second it's true. That
shouldn't happen.
Rainer, just pass CROSSOPT="-O-" for now until this issue is fixed. That
will disable optimization when building the compiler.
