* x86: fold SReg{2,3}Jan Beulich2019-07-161-0/+1
| | | | | | | | | | | | | | | They're the only exception to there generally being no mix of register kinds possible in an insn operand template, and there being two bits per operand for their representation is also quite wasteful, considering the low number of uses. Fold both bits and deal with the little bit of fallout. Also take the liberty and drop dead code trying to set REX_B: No segment register has RegRex set on it. Additionally I was quite surprised that PUSH/POP with the permitted segment registers is not covered by the test cases. Add the missing pieces.
* [gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AESMatthew Malcomson2019-07-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had mistakenly given all variants of the new SVE2 instructions pmull{t,b} a dependency on the feature +sve2-aes. Only the variant specifying .Q -> .D sizes should have that restriction. This patch fixes that mistake and updates the testsuite to have extra tests (matching the given set of tests per line in aarch64-tbl.h that the rest of the SVE2 tests follow). We also add a line in the documentation of the command line to clarify how to enable `pmull{t,b}` of this larger size. This is needed because all other instructions gated under the `sve2-aes` architecture extension are marked in the instruction documentation by an `HaveSVE2AES` check while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.

* [GAS, Arm] CLI with architecture sensitive extensionsAndre Vieira2019-04-011-7/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new framework to add architecture sensitive extensions, like GCC does. This patch also implements all architecture extensions currently available in GCC. This framework works as follows. To enable architecture sensitive extensions for a particular architecture, that architecture must contain an ARM_ARCH_OPT2 entry in the 'arm_archs' table. All fields here are the same as previous, with the addition of a new extra field at the end to <name> it's extension table. This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'. This struct can be filled with three types of entries: ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will enable <enable_bits> ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means +no<ext> will disable <disable_bits> ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set <disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext> will disable <disable_bits> (this is to be used instead of adding an ARM_ADD and ARM_REMOVE for the same <ext>) This patch does not disable the use of the old extensions, even if some of them are duplicated in the new tables. This is a "in-between-step" as we may want to deprecate the old table of extensions in later patches. For now, GAS will first look for the +<ext> or +no<ext> in the new table and if no entry is found it will continue searching in the old table, following old behaviour. If only an ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is used then it also continues to search the old table for it. A couple of caveats: - This patch does not enable the use of these architecture extensions with the '.arch_extension' directive. This is future work that I will tend to later. - This patch does not enable the use of these architecture extensions with the -mcpu option. This is future work that I will tend to later. - This patch does not change the current behaviour when combining an architecture extension and using -mfpu on the command-line. The current behaviour of GAS is to stage the union of feature bits enabled by both -march and -mfpu. GCC behaves differently here, so this is something we may want to revisit on a later date.

| | | | | | | | | | | | | | | | | | | "mtfsb0 4*cr7+lt" doesn't make all that much sense, but unfortunately glibc uses just that instead of "mtfsb0 28" to clear the fpscr xe bit.

* PowerPC @l, @h and @ha warnings, plus VLE e_liAlan Modra2018-12-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This patch add support to the Bulk Allocation Tag instructions from MTE. These are the following instructions added in this patch: - LDGV <Xt>, [<Xn|SP>]! - STGV <Xt>, [<Xn|SP>]! This needed a new kind of operand for the new addressing [<Xn|SP>]! since this has no offset and only takes a pre-indexed version. Hence AARCH64_OPND_ADDR_SIMPLE_2 and ldtdgv_indexed are introduced. (AARCH64_OPND_ADDR_SIMPLE fulfilled the no offset criteria but does not allow writeback). We also needed new encoding and decoding functions to be able to do the same. where <Xt> : Is the 64-bit destination GPR. <Xn|SP> : Is the 64-bit first source GPR or Stack pointer. *** include/ChangeLog *** 2018-11-12 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (aarch64_opnd): Add AARCH64_OPND_ADDR_SIMPLE_2.
