This patch started off just adding the warnings in tc-ppc.c about incorrect usage of @l, @h and @ha in instructions that don't have 16-bit D-form fields. That unfortunately showed up three warnings in ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like e_li r3, IV_table@l+0x00 which was being assembled to 8: 70 60 00 00 e_li r3,0 a: R_PPC_ADDR16_LO IV_table The ADDR16_LO reloc is of course completely bogus on e_li, which has a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800. Applying an ADDR16_LO reloc to the instruction potentially changes the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i, e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis, e_and2is, or some invalid encodings. Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was added 2017-09-05 but I can't see code in gas to generate the relocation. In any case, VLE_ADDR20 probably doesn't have the correct semantics for @l since ideally you'd want an @l to pair with @h or @ha to generate a 32-bit constant. Thus @l should only produce a 16-bit value, I think. So we need some more relocations to handle e_li it seems, or as I do in this patch, modify the behaviour of existing relocations when applied to e_li instructions. include/ * opcode/ppc.h (E_OPCODE_MASK, E_LI_MASK, E_LI_INSN): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw <R_PPC_VLE_ADDR20>): Correct mask and shift value. (ppc_elf_vle_split16): Use E_OPCODE_MASK. Handle e_li specially. gas/ * config/tc-ppc.c (md_assemble): Adjust relocs for VLE before TLS tweaks. Handle e_li. Warn on unexpected operand field for lo16/hi16/ha16 relocs. |
