From 64517994807b0d6bb3c6fd106f117c03242fac72 Mon Sep 17 00:00:00 2001 From: "Jose E. Marchesi" Date: Fri, 19 May 2017 09:27:08 -0700 Subject: binutils: support for the SPARC M8 processor This patch adds support for the new SPARC M8 processor (implementing OSA 2017) to binutils. New instructions: - Dictionary Unpack + dictunpack - Partitioned Compare with shifted result + Signed variants: fpcmp{le,gt,eq,ne}{8,16,32}shl + Unsigned variants: fpcmpu{le,gt}{8,16,32}shl - Partitioned Dual-Equal compared, with shifted result + fpcmpde{8,16,32}shl - Partitioned Unsigned Range Compare, with shifted result + fpcmpur{8,16,32}shl - 64-bit shifts on Floating-Point registers + fps{ll,ra,rl}64x - Misaligned loads and stores + ldm{sh,uh,sw,uw,x,ux} + ldm{sh,uh,sw,uw,x,ux}a + ldmf{s,d} + ldmf{s,d}a + stm{h,w,x} + stm{h,w,x}a + stmf{s,d} + stmf{s,d}a - Oracle Numbers + on{add,sub,mul,div} - Reverse Bytes/Bits + revbitsb + revbytes{h,w,x} - Run-Length instructions + rle_burst + rle_length - New crypto instructions + sha3 - Instruction to read the new register %entropy + rd %entropy New Alternate Address Identifiers: - 0x24, #ASI_CORE_COMMIT_COUNT - 0x24, #ASI_CORE_SELECT_COUNT - 0x48, #ASI_ARF_ECC_REG - 0x53, #ASI_ITLB_PROBE - 0x58, #ASI_DSFAR - 0x5a, #ASI_DTLB_PROBE_PRIMARY - 0x5b, #ASI_DTLB_PROBE_REAL - 0x64, #ASI_CORE_SELECT_COMMIT_NHT The new assembler command-line options for selecting the M8 architecture are: -Av9m8 or -Asparc6 for 64-bit binaries. -Av8plusm8 for 32-bit (v8+) binaries. The corresponding disassembler command-line options are: -msparc:v9m8 for 64-bit binaries. -msparc:v8plusm8 for 32-bit (v8+) binaries.
