[DebugInfo] Drop stale entry value-limitation for call site values (#172340)
Entry value operations could previously not be combined with other
operations in debug expressions, meaning that we had to skip emitting
call site values in such cases. This DIExpression limitation was removed
in 57a371d7010802804343d17b85ac5e0d28d0f309, so we should be free to
emit call site values for such cases now, for example:
extern void call(int, int);
void entry_value (int param) {
call(param + 222, param - 444);
}
This change exposed a call site parameter entry order issue in the
dbgcall-site-expr-entry-value.mir test case. That ordering issue is
tracked in #43998, and I don't think there is anything inherent in this
patch that caused that.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
