2024-09-20[Object][NFC] Add extern template declarations needed by llvm-objdump (#109156)Thomas Fransham1-10/+13
These symbols are implicitly imported from the LLVM shared library by llvm-objdump on ELF like platforms, but for windows they need to be explicitly exported when LLVM is built as shared library. I also add visibility macros for XCOFFObjectFile::getExceptionEntries that can't automatically be added by clang tooling since it doesn't store the source locations for explicit function template instantiations.

The section headers for XCOFF files have a subtype flag for Dwarf sections. This PR updates obj2yaml, yaml2obj, and llvm-readobj so that they recognize the subtype.
2023-11-26[XCOFF] make related SD symbols as isFunction (#69553)Chen Zheng1-10/+46

2023-11-15[XCOFF]refactor isFunction, NFC (#72232)Chen Zheng1-14/+10
suggested in review of https://github.com/llvm/llvm-project/pull/69553 This is actually not an NFC as isFunction() does not return false for some "invalid" object, instead it returns the errors to its caller. But since there is no such invalid object in the LIT tests, so no case changes.
2023-10-12[XCOFF][OBJECT] get symbol size by calling XCOFF interfaces (#67304)Chen Zheng1-11/+16
Computing the symbol size as the gap between sorted symbols are not right for XCOFF. For XCOFF, the size info is stored in aux symbol and can be got from existing XCOFF interface `getSymbolSize()`. This patch changes XCOFFObjectFile to call this API to get sizes for symbols.
2023-07-13[PowerPC][MC] Set 'future' as default CPU type of XCOFFQiu Chaofan1-0/+4
For Power on Linux (both LE and BE), ELFObjectFile returns 'future' as default CPU type if mcpu is not specified, so that all necessary features will be enabled in MC. While for XCOFF, the default CPU type is always null, which makes tools like llvm-objdump not able to recognize prefixed instructions, unless specifying --mcpu=pwr10 or --mattr=+prefix-instrs manually.

2023-06-26Move SubtargetFeature.h from MC to TargetParserJob Noorman1-1/+1
SubtargetFeature.h is currently part of MC while it doesn't depend on anything in MC. Since some LLVM components might have the need to work with target features without necessarily needing MC, it might be worthwhile to move SubtargetFeature.h to a different location. This will reduce the dependencies of said components. Note that I choose TargetParser as the destination because that's where Triple lives and SubtargetFeatures feels related to that. This issues came up during a JITLink review (D149522). JITLink would like to avoid a dependency on MC while still needing to store target features.

2023-01-05Move from llvm::makeArrayRef to ArrayRef deduction guides - llvm/ partserge-sans-paille1-1/+1
Use deduction guides instead of helper functions. The only non-automatic changes have been: 1. ArrayRef(some_uint8_pointer, 0) needs to be changed into ArrayRef(some_uint8_pointer, (size_t)0) to avoid an ambiguous call with ArrayRef((uint8_t*), (uint8_t*)) 2. CVSymbol sym(makeArrayRef(symStorage)); needed to be rewritten as CVSymbol sym{ArrayRef(symStorage)}; otherwise the compiler is confused and thinks we have a (bad) function prototype. There was a few similar situation across the codebase. 3. ADL doesn't seem to work the same for deduction-guides and functions, so at some point the llvm namespace must be explicitly stated. 4. The "reference mode" of makeArrayRef(ArrayRef<T> &) that acts as no-op is not supported (a constructor cannot achieve that). Per reviewers' comment, some useless makeArrayRef have been removed in the process. This is a follow-up to https://reviews.llvm.org/D140896 that introduced the deduction guides.

2021-10-11[Object] Deduplicate the three createError functionsRaphael Isemann1-4/+0
The Object library currently has three identical functions that translate a Twine into a parser error. Until recently these functions have coexisted peacefully, but since D110320 Clang with enabled modules is now diagnosing that we have several definitions of `createError` in Object. This patch just merges them all and puts them into Object's `Error.h` where the error code for `parse_failed` is also defined which seems cleaner and unbreaks the bots.
