// AArch32 ENCODING TABLE

// =============================================================================
|
||
//
|
||
// Comprehensive encoding catalog for AArch32 (A32 + T32 + Thumb-1 + VFP + NEON
|
||
// + ARMv8 crypto/CRC). Each entry: `{mnemonic, ops[4], enc[4], bits, mask,
|
||
// feature, mode, flags}`. The matcher tests `(word & mask) == bits`; the
|
||
// encoder OR's operand bits into the zero positions of `mask`.
|
||
//
|
||
// Layout of the file is by section:
|
||
//
|
||
// §1 A32 data processing -- immediate / register / register-shifted-register
|
||
// §2 A32 multiply family
|
||
// §3 A32 saturating arithmetic + ARMv6 DSP SIMD on GPRs
|
||
// §4 A32 extends + bit-field + REV + CLZ + RBIT + SEL + PKHBT/TB
|
||
// §5 A32 branches + status reg + exception generation
|
||
// §6 A32 load/store (word/byte/halfword/doubleword + LDM/STM + SWP)
|
||
// §7 A32 exclusive monitors + acquire/release + barriers + hints
|
||
// §8 A32 coprocessor (CDP/MCR/MRC/LDC/STC) + CRC32 + AES/SHA
|
||
// §9 A32 VFP scalar floating point (VFPv2/v3/v4)
|
||
// §10 A32 Advanced SIMD (NEON) -- vector arithmetic + load/store
|
||
// §11 T16 Thumb-1 (16-bit) encodings
|
||
// §12 T32 Thumb-2 (32-bit) encodings
|
||
// §13 VFP / NEON Thumb-2 encodings (when distinct)
|
||
//
|
||
// Conventions:
|
||
// * A32 conditional instructions have bits 31:28 (cond) as OPERAND-driven.
|
||
// The static `bits` contain 0 for those positions, and `mask` doesn't lock
|
||
// them. The encoder OR's the user-supplied cond into bits 31:28 when the
|
||
// entry's flags.cond_in_28 is true. For UNCONDITIONAL classes (top nibble
|
||
// 1111), we set bits 31:28 = 1111 and mask locks them, and flags.cond_in_28
|
||
// is false.
|
||
//
|
||
// * Set-flags variants (ADDS, SUBS, ANDS, ...) are SEPARATE entries with
|
||
// bit 20 (S) set in `bits` and locked by `mask`. The mnemonic is shared
|
||
// with the non-flag-setting form -- the encoder picks based on the
|
||
// `sets_flags` flag on the user's Instruction.
|
||
//
|
||
// * For T32 32-bit (Thumb-2) entries, `bits` packs (low_halfword |
|
||
// high_halfword << 16). E.g. a Thumb-2 encoding with low=0xF000 and
|
||
// high=0xF800 stores as 0xF800F000.
