From 672a303852353ba9299f6f50190fca8b3abe4c1d Mon Sep 17 00:00:00 2001 From: Yann Sionneau Date: Fri, 2 Oct 2020 16:24:55 +0200 Subject: kvx: add support for kvx arch to uClibc-ng MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds support for Kalray VLIW family (kvx) Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the third of the KV family has the following features: 32/64 bits execution mode 6-issue VLIW architecture 64 x 64bits general purpose registers SIMD instructions little-endian In order to build a usable toolchain, build scripts are provided at the following address: https://github.com/kalray/build-scripts. Kalray uses FOSS which is available at https://github.com/kalray This includes Linux kernel, uClibc-ng, gcc, binutils, etc. Signed-off-by: Clément Léger Signed-off-by: Guillaume Thouvenin Signed-off-by: Laurent Thevenoux Signed-off-by: Marc Poulhies Signed-off-by: Marius Gligor Signed-off-by: Yann Sionneau --- include/elf.h | 87 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 86 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/elf.h b/include/elf.h index d1be3bc1b..7d66d70a4 100644 --- a/include/elf.h +++ b/include/elf.h @@ -273,9 +273,10 @@ typedef struct #define EM_ARCV2 195 /* ARCv2 Cores */ #define EM_RISCV 243 /* RISC-V */ #define EM_CSKY 252 /* C-SKY Cores */ +#define EM_KVX 256 /* Kalray VLIW core of the MPPA processor family */ /* NEXT FREE NUMBER: Increment this after adding your official arch number */ -#define EM_NUM 253 +#define EM_NUM 257 /* If it is necessary to assign new unofficial EM_* values, please pick large random numbers (0x8523, 0xa7f2, etc.) to minimize the chances of collision @@ -1253,6 +1254,90 @@ typedef struct #define ELF64_M_SIZE(info) ELF32_M_SIZE (info) #define ELF64_M_INFO(sym, size) ELF32_M_INFO (sym, size) +/* KVX relocs */ +#define R_KVX_NONE 0 +#define R_KVX_16 1 +#define R_KVX_32 2 +#define R_KVX_64 3 +#define R_KVX_S16_PCREL 4 +#define R_KVX_PCREL17 5 +#define R_KVX_PCREL27 6 +#define R_KVX_32_PCREL 7 +#define R_KVX_S37_PCREL_LO10 8 +#define R_KVX_S37_PCREL_UP27 9 +#define R_KVX_S43_PCREL_LO10 10 +#define R_KVX_S43_PCREL_UP27 11 +#define R_KVX_S43_PCREL_EX6 12 +#define R_KVX_S64_PCREL_LO10 13 +#define R_KVX_S64_PCREL_UP27 14 +#define R_KVX_S64_PCREL_EX27 15 +#define R_KVX_64_PCREL 16 +#define R_KVX_S16 17 +#define R_KVX_S32_LO5 18 +#define R_KVX_S32_UP27 19 +#define R_KVX_S37_LO10 20 +#define R_KVX_S37_UP27 21 +#define R_KVX_S37_GOTOFF_LO10 22 +#define R_KVX_S37_GOTOFF_UP27 23 +#define R_KVX_S43_GOTOFF_LO10 24 +#define R_KVX_S43_GOTOFF_UP27 25 +#define R_KVX_S43_GOTOFF_EX6 26 +#define R_KVX_32_GOTOFF 27 +#define R_KVX_64_GOTOFF 28 +#define R_KVX_32_GOT 29 +#define R_KVX_S37_GOT_LO10 30 +#define R_KVX_S37_GOT_UP27 31 +#define R_KVX_S43_GOT_LO10 32 +#define R_KVX_S43_GOT_UP27 33 +#define R_KVX_S43_GOT_EX6 34 +#define R_KVX_64_GOT 35 +#define R_KVX_GLOB_DAT 36 +#define R_KVX_COPY 37 +#define R_KVX_JMP_SLOT 38 +#define R_KVX_RELATIVE 39 +#define R_KVX_S43_LO10 40 +#define R_KVX_S43_UP27 41 +#define R_KVX_S43_EX6 42 +#define R_KVX_S64_LO10 43 +#define R_KVX_S64_UP27 44 +#define R_KVX_S64_EX27 45 +#define R_KVX_S37_GOTADDR_LO10 46 +#define R_KVX_S37_GOTADDR_UP27 47 +#define R_KVX_S43_GOTADDR_LO10 48 +#define R_KVX_S43_GOTADDR_UP27 49 +#define R_KVX_S43_GOTADDR_EX6 50 +#define R_KVX_S64_GOTADDR_LO10 51 +#define R_KVX_S64_GOTADDR_UP27 52 +#define R_KVX_S64_GOTADDR_EX27 53 +#define R_KVX_64_DTPMOD 54 +#define R_KVX_64_DTPOFF 55 +#define R_KVX_S37_TLS_DTPOFF_LO10 56 +#define R_KVX_S37_TLS_DTPOFF_UP27 57 +#define R_KVX_S43_TLS_DTPOFF_LO10 58 +#define R_KVX_S43_TLS_DTPOFF_UP27 59 +#define R_KVX_S43_TLS_DTPOFF_EX6 60 +#define R_KVX_S37_TLS_GD_LO10 61 +#define R_KVX_S37_TLS_GD_UP27 62 +#define R_KVX_S43_TLS_GD_LO10 63 +#define R_KVX_S43_TLS_GD_UP27 64 +#define R_KVX_S43_TLS_GD_EX6 65 +#define R_KVX_S37_TLS_LD_LO10 66 +#define R_KVX_S37_TLS_LD_UP27 67 +#define R_KVX_S43_TLS_LD_LO10 68 +#define R_KVX_S43_TLS_LD_UP27 69 +#define R_KVX_S43_TLS_LD_EX6 70 +#define R_KVX_64_TPOFF 71 +#define R_KVX_S37_TLS_IE_LO10 72 +#define R_KVX_S37_TLS_IE_UP27 73 +#define R_KVX_S43_TLS_IE_LO10 74 +#define R_KVX_S43_TLS_IE_UP27 75 +#define R_KVX_S43_TLS_IE_EX6 76 +#define R_KVX_S37_TLS_LE_LO10 77 +#define R_KVX_S37_TLS_LE_UP27 78 +#define R_KVX_S43_TLS_LE_LO10 79 +#define R_KVX_S43_TLS_LE_UP27 80 +#define R_KVX_S43_TLS_LE_EX6 81 + /* C-SKY relocs. */ #define R_CKCORE_NONE 0 -- cgit v1.2.3
