R_CUDA Relocation Catalog

Complete reference table of all 119 R_CUDA relocation type names extracted from nvlink v13.0.88. Types are organized into two descriptor tables: the standard table at off_1D37600 (117 entries, indices 0--116) and the attribute table at off_1D371E0 (65 entries, indices 0x10000--0x10040). See R_CUDA Relocations for the relocation engine, descriptor format, action types, and architecture class system.

Standard Table (off_1D37600)

117 entries. Index = raw r_type value in .rela.* sections. Bit width and bit position are derived from the type name and confirmed against the 64-byte descriptors at off_1D3DBE0.

Attribute Table (off_1D371E0)

65 entries. Attribute relocations apply to .nv.info.* metadata sections rather than instruction streams. The encoded r_type in ELF is 0x10000 + index (e.g., attribute index 3 = r_type 0x10003). The attribute table reuses a subset of the same type names as the standard table but with different 64-byte descriptors.

The attribute table entries are not individually named in the binary -- they share string pointers with the standard table. The following mapping lists the 65 attribute indices and the standard-table name each one references. Indices not listed here (gaps) use R_CUDA_NONE.

Confidence Assessment

Verification scope: All 117 standard-table names and 65 attribute-table indices were cross-checked against nvlink_strings.json (exact-string match) and the decompiled table dispatcher sub_42F6C0 (nvlink/decompiled/sub_42F6C0_0x42f6c0.c). Ten entries were spot-checked end-to-end: string presence, string address, and relocation-engine consumption of off_1D3DBE0.

Totals: 117 standard entries + 65 attribute entries = 182 catalog rows. String verification: 119 / 119 raw strings in nvlink_strings.json (includes two trailing-whitespace duplicates of R_CUDA_UNIFIED_8_0 and R_CUDA_UNIFIED_8_8 at 0x1d3cb9f / 0x1d3cbb3) collapse to the 117 canonical names after trimming. Verified: 117 / 117 canonical names. Unverified: 0.

Spot-check table (10 entries)

Entry	Confidence	Evidence
`R_CUDA_NONE` (idx 0)	HIGH	String at `0x1D35F60` (`nvlink_strings.json`); dispatched via `off_1D37600[0]` in `sub_42F6C0` (line 25); sentinel no-op path in relocation engine
`R_CUDA_G64` (idx 4)	HIGH	String at `0x1D35F8B`; reachable via `off_1D37600[4]` in `sub_42F6C0`; descriptor consumed by `sub_469620` (line 27: `v8 = &off_1D3DBE0`)
`R_CUDA_TEX_HEADER_INDEX` (idx 6)	HIGH	String at `0x1D35FA6`; texture-binding path in bindless relocation engine
`R_CUDA_CONST_FIELD19_28` (idx 24)	HIGH	String at `0x1D36108`; 19-bit bitfield encoding at position 28 matches the name suffix
`R_CUDA_FUNC_DESC_32` (idx 34)	HIGH	String at `0x1D361E4`; descriptor table entry consumed by `sub_46ADC0` (line 135: `v90 = &off_1D3DBE0`) -- resolved relocations emitter
`R_CUDA_PCREL_IMM24_26` (idx 40)	HIGH	String at `0x1D3626B`; PC-relative branch handler in relocation engine
`R_CUDA_INSTRUCTION64` (idx 53)	HIGH	String at `0x1D3637E`; whole-instruction replacement path in `sub_469D60` (line 214: `v152 = &off_1D3DBE0`)
`R_CUDA_BINDLESSOFF14_40` (idx 65)	HIGH	String at `0x1D36471`; bindless-offset handler in texture relocation pipeline
`R_CUDA_YIELD_OPCODE9_0` (idx 68)	HIGH	String at `0x1D364B7`; YIELD-opcode rewrite path in `sub_469D60`; cross-referenced in ptxas wiki (`relocations.md` line 244)
`R_CUDA_NONE_LAST` (idx 116)	HIGH	String at `0x1D36808`; end-of-range sentinel -- bounds `a1 >= 0x75` check in `sub_42F6C0` (line 26)

Cross-reference with the ptxas Relocations page: The ten spot-checked names match verbatim against ptxas lines 80, 124, 140, 155, 179, 195, 217, 242, 244, 248. No ordinal drift between ptxas and nvlink for these entries.

Aspect	Confidence	Basis
Type names (all 117 entries)	HIGH	117/117 canonical names found in `nvlink_strings.json` at addresses `0x1D35F60`--`0x1D36808` (contiguous string-pool region); no missing entries
Standard table address (`off_1D37600`)	HIGH	Confirmed in decompiled `sub_42F6C0` line 25 (`v7 = &off_1D37600`); bounds check `a1 >= 0x75` (117 = 0x75) at line 26
Attribute table address (`off_1D371E0`)	HIGH	Confirmed in decompiled `sub_42F6C0` line 17 (`v7 = &off_1D371E0`); bounds check `a1 < 0x41` (65 = 0x41) at line 18 after `a1 -= 0x10000`
Descriptor table address (`off_1D3DBE0`)	HIGH	Referenced by three relocation engines: `sub_469620` (line 27), `sub_46ADC0` (line 135), `sub_469D60` (line 214)
Entry count (117 standard, 65 attribute)	HIGH	Table bounds encoded as immediate constants in `sub_42F6C0`: `v6 = 117` (line 24) and `v6 = 65` (line 16)
Index-to-name mapping	HIGH	Name strings are stored as 16-byte records (ptr, 3xDWORD metadata) at `off_1D37600`; `sub_42F6C0` line 29: `v8 = &v7[2 * a1]` confirms 16-byte stride
Bit width / bit position columns	MEDIUM	Parsed by this catalog from type-name suffix convention (`ABS32_26` = 32-bit field at bit 26); the 64-byte descriptors at `off_1D3DBE0` encode these values but were not byte-for-byte decoded for every entry
Category classification	MEDIUM	Inferred from naming patterns (`ABS` = absolute, `PCREL` = PC-relative, `CONST_FIELD` = constant bank, `FUNC_DESC` = function descriptor, etc.); no explicit category field in the binary
Attribute table shared-name mapping	MEDIUM	Attribute entries at `off_1D371E0` share string pointers with the standard table at `off_1D37600` by pointer equality; the 1:1 index mapping is inferred from array position, not from an explicit mapping table. Gaps in the attribute table (e.g. indices beyond 0x40) fall through to the `"unknown attribute"` diagnostic at `sub_42F6C0` line 21
Action-code bit-field interpretation	LOW	The 64-byte descriptor layout at `off_1D3DBE0` (bit width, shift, action enum, arch-class bitmask) is inferred from consumer code patterns in `sub_469620`/`sub_46ADC0`/`sub_469D60`, not documented as a concrete struct in the binary
