CMakeLists.txt	[OpenMP][OMPD] libompd must not link libomp (#83119) Fixes a regression introduced in 91ccd8248. The code for libompd includes kmp.h for enum kmp_sched. The dependency to hwloc is not necessary. Avoid the dependency by skipping the definitions in kmp.h using types from hwloc.h. Fixes #80750	2 年前
Debug.h	[OpenMP][OMPD] Implementation of OMPD debugging library - libompd. This is a continuation of the review: https://reviews.llvm.org/D100181 Creates a new directory "libompd" under openmp. "TargetValue" provides operational access to the OpenMP runtime memory for OMPD APIs. With TargetValue, using "pointer" a user can do multiple operations from casting, dereferencing to accessing an element for structure. The member functions are designed to concatenate the operations that are needed to access values from structures. e.g., _a[6]->_b._c would read like : TValue(ctx, "_a").cast("A",2) .getArrayElement(6).access("_b").cast("B").access("_c") For example: If you have a pointer "ThreadHandle" of a running program then you can access/retrieve "threadID" from the memory using TargetValue as below. TValue(context, thread_handle->th) /__kmp_threads[t]->th/ .cast("kmp_base_info_t") .access("th_info") /__kmp_threads[t]->th.th_info/ .cast("kmp_desc_t") .access("ds") /__kmp_threads[t]->th.th_info.ds/ .cast("kmp_desc_base_t") .access("ds_thread") /__kmp_threads[t]->th.th_info.ds.ds_thread/ .cast("kmp_thread_t") .getRawValue(thread_id, 1); Reviewed By: @hbae Differential Revision: https://reviews.llvm.org/D100182	4 年前

TargetValue.h	[ompd] Fix strict aliasing violation in TargetValue::getValue() (#97739) For the case where baseTypeSize does not match the size of T, read the value into a separate char buffer first. This avoids accessing buf using two different types. Fixes https://github.com/llvm/llvm-project/issues/94616.	2 年前
