switching to newer linux-libc-dev linux-2.6 provided kernel headers worked fine beside on mips mipsel: In file included from usr/klibc/arch/mips/crt0.S:11: usr/include/arch/mips/machine/asm.h:8:24: error: asm/regdef.h: No such file or directory usr/include/arch/mips/machine/asm.h:9:21: error: asm/asm.h: No such file or directory i'm not sure if you want to export both headers in the make kernelheaders target or if it is the fault of klibc to assume that those are available? -- maks

...there is no difference between input and output operands for memory constraints. can somebody confirm this? i could not find documentation on these flags, following the AddInlineAsmOperands it seems to be something like: 'Code | (Size << 3)' with Code on of these values: 1 REGUSE 2 REGDEF 3 IMM 4 MEM/ADDR are there any other values? and would it be safe to change 4 to MEMUSE and add 5 (MEMDEF)? i do not know where these values are used (except for the ISelDAG and the AsmPrinter). florian

Hi, On SystemZ there are a set of "access registers" that can be copied in and out of 32-bit GPRs with special instructions. These instructions can only perform the copy using low 32-bit parts of the 64-bit GPRs. As reported and discussed at https://bugs.llvm.org/show_bug.cgi?id=44254, this is currently broken due to the fact that the default register class for 32-bit integers is

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
