This is an important patch needed by Linux Kernel security project. compared to the 9th patch, the ONLY change is: I split the 1st patch into the following two patches: patch 1/3: Introduce IR bit TYPE_INCLUDES_FLEXARRAY for the GCC extension [PR77650] patch 3/3: Use TYPE_INCLUDES_FLEXARRAY in __builtin_object_size[PR101832] so, in patch 1/3 includes all the FE changes, changes in Middle-end to support the FE changes. patch 3/3 only includes the change in gcc/tree-object-size.cc and the testing case to support PR101832. Now, there are 3 patches: patch 1/3: Introduce IR bit TYPE_INCLUDES_FLEXARRAY for the GCC extension [PR77650] patch 2/3: Update documentation to clarify a GCC extension [PR77650] patch 3/3: Use TYPE_INCLUDES_FLEXARRAY in __builtin_object_size[PR101832] among the above, the patch 1/3 and the patch 2/3 have been reviewed and approved. the patch 3/3 is a very simple change to use the new bit TYPE_INCLUDES_FLEXARRAY in __builtin_object_size. I have bootstrapped and regression-tested on both aarch64 and x86. no issues. I will commit the patch 1/3 and 2/3 tomorrow since they have been approved already. for the patch 3/3, I will wait for several days, if there is no objection or new comments, I will commit it the end of this week. Please let me know if you have comments and suggestions. thanks.
