As best as I am able to infer from reading the code, this value is only meant to be used for reporting relocations of RIP-relative addresses, which x86 doesn't have.

Fixes#79170.

No diffs are expected.

The value is used to compensate for the additional instruction bytes,
which should only be relevant for RIP-relative addressing, while x86
uses absolute addressing.

This seems like a reasonable fix, but I wonder if we should consider this a crossgen2 bug.

I wrote a fix there that seems to work: #79627

This matches the behavior that the old ngen tool had: ignore addlDelta except for REL32 relocs, and the IMAGE_REL_BASED_DISP32 "pseudo-reloc" used here only maps to REL32 on x64; it maps to HIGHLOW on x86.

Indeed, that was the main question here. What made me prefer a fix in the Jit was that it is easier to understand: there is no computation of data on one side where the other is expected to explicitly ignore it for things to work properly.

This seems like a reasonable fix, but I wonder if we should consider this a crossgen2 bug.
I wrote a fix there that seems to work: #79627
This matches the behavior that the old ngen tool had: ignore addlDelta except for REL32 relocs, and the IMAGE_REL_BASED_DISP32 "pseudo-reloc" used here only maps to REL32 on x64; it maps to HIGHLOW on x86.

Indeed, that was the main question here. What made me prefer a fix in the Jit was that it is easier to understand: there is no computation of data on one side where the other is expected to explicitly ignore it for things to work properly.

As best as I am able to infer from reading the code, this value is only meant to be used for reporting relocations of RIP-relative addresses, which x86 doesn't have.
Fixes#79170.
No diffs are expected.

The value is used to compensate for the additional instruction bytes,
which should only be relevant for RIP-relative addressing, while x86
uses absolute addressing.
