...o solve. Is that right? That depends. The register allocator can spill across register classes, but it calls the functionality "live range splitting" and "register class inflation". Here's how you enable it: - Define a union register class that contains both CPU64Regs and ACRegs. - Implement TRI::getLargestLegalSuperClass(), and return the new union register class when asked about CPU64Regs or ACRegs (or their sub-classes). - Teach TII::copyPhysReg() to handle the cross-class copies. - Teach TII::storeRegToStackSlot() to constrain the register class to CPU64Regs when as...

Hi Jakob, I believe Hal is trying to enable register scavenger to find two (or more) registers that can be used as temporaries. One problem I see with this approach is that, if you use register scavenger during PEI, you will have to pessimistically set aside two emergency spill slots before you call scavengeRegister, even if it turns out you only need one. Having an extra stack slot might not be

The in-kernel nfsroot code is obsoleted by kinit. Remove it; it causes conflicts. Signed-off-by: H. Peter Anvin <hpa at zytor.com> --- commit 161e1dc16ec1129b30b634a2a8dcbbd1937800c5 tree c30da837d746fe65d8a13ccf6f27bd381948edb4 parent 018604e070e143657abcf0cb256a1e2dda205d97 author H.

This patch removes support for use of NFS as a root filesystem from the kernel. It also updates the documentation to reflect this. b/Documentation/nfsroot.txt | 97 +++--- b/arch/arm/def-configs/a5k | 1 b/arch/arm/def-configs/adi_evb | 1 b/arch/arm/def-configs/adsbitsy | 1 b/arch/arm/def-configs/anakin | 1
