Result is comparable to the result I got with the current version of those packages: make CROSS_COMPILE=powerpc64-linux-gnu- ARCH=powerpc drivers/dma/ppc4xx/adma.o [...] {standard input}: Assembler messages: {standard input}:2122: Error: junk at end of line: `128' {standard input}:2367: Error: junk at end of line: `128' {standard input}:5136: Error: junk at end of line: `1' {standard input}:5165: Error: junk at end of line: `1' {standard input}:5174: Error: junk at end of line: `1' make[1]: *** [drivers/dma/ppc4xx/adma.o] Error 1 make: *** [drivers/dma/ppc4xx/adma.o] Error 2 make CROSS_COMPILE=powerpc64-linux-gnu- ARCH=powerpc CFLAGS_adma.o="-S" drivers/dma/ppc4xx/adma.o CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CALL scripts/checksyscalls.sh CC drivers/dma/ppc4xx/adma.o sed -n -e "2122p; 2367p; 5136p; 5165p; 5174p" drivers/dma/ppc4xx/adma.o mfcr 9,128 mfcr 9,128 mfcr 9,1 mfcr 9,1 mfcr 9,1 So this is apparently not some gcc regression. Now Fedora doesn't care anymore about PPC32. On the other hand it does provide _kernel_ cross builders for almost all current kernel architectures. So apparently Fedora hopes to cover as many kernel builds as is possible. Did I get that right? So would it be worth David's (mostly) and my (a little) time to try to get at least 32 bit PPC code to build?
