[StrTable] Use string literal emission for intrinsics on non-MSVC platforms (#124856) 2025-04-13T15:58:53+00:00 Reid Kleckner rnk@google.com 2025-04-13T15:58:53+00:00 0a27c4e318e778b520306a9e2102e03023cfaa33 This mainly transitions the LLVM intrinsic string table from character emission to string literal emission, which I confirmed happens for me locally. I moved the guts of StringToOffsetTable to a cpp file so I could move the `EmitLongStrLiterals` cl::opt global to a non-vague linkage home in the `TableGen` library. I had to add missing FormatVariadic.h includes to account for moving other includes to a cpp file.

 [TableGen] Use std::pair instead of std::make_pair. NFC.

 [TableGen] Allow empty terminator in SequenceToOffsetTable (#119751) 2024-12-13T16:55:11+00:00 Sergei Barannikov barannikov88@gmail.com 2024-12-13T16:55:11+00:00 c9070cce09e1aef1c4bf1cb8c0000294b533dcd7 Some clients do not want to emit a terminator after each sub-sequence (they have other means of determining the length of sub-sequences). This moves `Term` argument from `emit` method to the constructor and makes it optional. It couldn't be made optional while still on the `emit` method because if the terminator wasn't specified, it has to be taken into account in `layout` method as well. The fact that `layout` method was called is now recorded in a dedicated member variable, `IsLaidOut`. `Entries != 0` can no longer be used to reliably check if `layout` method was called because it may be zero for a different reason: the terminator wasn't specified and all added sequences (if any) were empty. This reduces the size of `*LaneMaskLists` and `*SubRegIdxLists` a bit and resolves the removed TODO.
