In the discussion around #116792, @rjmccall mentioned that ARCMigrate
has been obsoleted and that we could go ahead and remove it from Clang,
so this patch does just that.
For example, `include/llvm/DebugInfo/DWARF/DWARFContext.h` is included
as part of both the generic "DebugInfo" target as well as the specific
"DebugInfoDWARF" target. It should only be in one. Tooling that manages
build dependencies should be more accurate now.
This commit introduces a new MathToEmitC conversion pass that lowers
selected math operations from the Math dialect to the emitc.call_opaque
operation in the EmitC dialect.
**Supported Math Operations:**
The following operations are converted:
- math.floor -> emitc.call_opaque<"floor">
- math.round -> emitc.call_opaque<"round">
- math.exp -> emitc.call_opaque<"exp">
- math.cos -> emitc.call_opaque<"cos">
- math.sin -> emitc.call_opaque<"sin">
- math.acos -> emitc.call_opaque<"acos">
- math.asin -> emitc.call_opaque<"asin">
- math.atan2 -> emitc.call_opaque<"atan2">
- math.ceil -> emitc.call_opaque<"ceil">
- math.absf -> emitc.call_opaque<"fabs">
- math.powf -> emitc.call_opaque<"pow">
**Target Language Standards:**
The pass supports targeting different language standards:
- C99: Generates calls with suffixes (e.g., floorf, fabsf) for
single-precision floats.
- CPP11: Prepends std:: to functions (e.g., std::floor, std::fabs).
**Design Decisions:**
The pass uses emitc.call_opaque instead of emitc.call to better emulate
C-style function overloading.
emitc.call_opaque does not require a unique type signature, making it
more suitable for operations like <math.h> functions that may be
overloaded for different types.
This design choice ensures compatibility with C/C++ conventions.
This target exists to allow `#include "Header.h"` for headers in
lib/Basic rather than using file-relative inclusion. This is rather
hacky and results in having two targets that claim the same headers.
Instead, we can pass a `-I` flag in the `copts` for //clang:basic, to
adjust the include path to keep those `#include "Header.h"` directives
working. There are other targets in this file already doing a similar
thing for generated files.
We're currently excluding Wasm.cpp, because it requires emscripten. When
using header modules, Wasm.h gets compiled on its own and it also
requires emscripten, so we need to exclude both.
The Frontend library depends on Serialization. This is an explicit
dependency encoded in the CMake target. However, Serialization currently
has an implicit dependency on Frontend, as it includes one of its
headers. This is not reflected in the CMake build rules, but Bazel is
stricter so, in order to avoid a dependency cycle, it hackily declares
the Frontend headers as source files for Serialization.
Fortunately, the only Frontend header used by Serialization is
clang/Frontend/FrontendDiagnostic.h, which is a legacy header that just
includes clang/Basic/DiagnosticFrontend since
d076608d58, back in 2018.
This commit changes Serialization to use the underlying header from
Basic instead. Both Serialization and Frontend depend on Basic, so this
breaks the dependency cycle.
These are unneeded even on AIX, PURE_WINDOWS, and ZOS (per #104706)
* HAVE_ERRNO_H: introduced by 1a93330ffa (2009) but unneeded.
The guarded ABI is unconditionally used by lldb.
* HAVE_FCNTL_H
* HAVE_FENV_H
* HAVE_SYS_STAT_H
Pull Request: https://github.com/llvm/llvm-project/pull/123087
Adds:
1. tosa shape type to Tosa dialect e.g., !tosa.shape<4> is a type for
rank-4 shape values (size-4 array of index values)
2. const_shape operator
3. trait TosaShapeOperator, added to tosa shape operators, and a
verifier that all operands and results of operator are tosa shapes
4. trait TosaResolvableShapeOperands, added to all tosa operators, and a
verifier that every tosa shape operand is produced by a tosa shape
operator (indicated by trait TosaShapeOperator)
5. trait TosaShapeOperatorWithSameRanks, added to
Tosa_ElementwiseShapeOp and a verifier that all operands and result
shapes have same ranks
5. changed TileOp's multiples from attribute to input, of !tosa.shape
type.
6. add folder for tosa ConstShape operator

Added `# keep sorted` to a couple of long-ish lists of files that
buildifier didn't automatically sort by default.
Changed a couple of one-element `toolchains` attributes to the
single-line format.
