Hi Akira, If I follow correctly, the relocation entries can thus be in a different order than the instructions that they're for? That seems a bit odd, but I suppose there's nothing inherently wrong with that. It's just not something, AFAIK, that llvm has had to deal with before. This should definitely be a target-specific thing, not a general ELFObjectWriter thing, as other targets

What would be the best way to sort relocation entries before they are written out in ELFObjectWriter::WriteRelocationsFragment? According to the Mips ABI documents I have, there are certain restrictions on the order relocations appear in the table (e.g. R_MIPS_HI16 and R_MIPS_GOT16 must be followed immediately by a R_MIPS_LO16). When I enable post RA scheduling, some of the restrictions are

Hi Jan, After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times. Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times. (It also stalls on shutdown BTW) I have
