2025-05-21internal/pkgbits: specify that RelIdx is an element indexMark Freeman
Without this, it's not clear what this is relative to or the granularity of the index.

2025-05-12internal/pkgbits: rename Reloc* to Section*Mark Freeman
This is a basic refactoring. This enumeration refers primarily to the different sections of a UIR file, so this naming is a bit more direct.

2025-05-06pkgbits: alias RelocKind with a SectionKind typeMark Freeman
I think that SectionKind better conveys the original intent here, and goes nicely with codifying section relative indices.

2024-08-20internal/pkgbits: add Version typeTim King
Adds a new Version type to pkgbits to represent the version of the bitstream. Versions let readers and writers know when different data is expected to be present or not in the bitstream. These different pieces of data are called Fields, as an analogy with fields of a struct. Fields can be added, removed or changed in a Version. Extends Encoder and Decoder to report which version they are.

2022-07-12internal/pkgbits: change EnableSync into a dynamic knobMatthew Dempsky
Rather than requiring users to recompile the compiler and all tools to enable/disable sync markers, this CL adds a flag word into the Unified IR file format to allow indicating whether they're enabled or not. This in turn requires bumping the file format version. Thanks to drchase@ for benchmarks showing this isn't as expensive as I feared it would be.

So far unified IR has been relying on the backwards-compat iexport data to supply package fingerprints for imports. To be able to drop the iexport data and natively use unified IR everywhere. This CL applies basically the same idea that iexport used: simply hash all of the export data as it's being written out, and then tack on an 8-byte hash at the end.
