41426714: Print specific categories with incompatible ABIs in warning message #19986

Open openradar-mirror opened 6 years ago

Description

Summary: If you have multiple pre-compiled binaries that were built with different Objective-C compiler versions, ld can produce this warning:

Some object files have incompatible Objective-C category definitions. Some category metadata may be lost. All files containing Objective-C categories should be built using the same compiler.

It would be very useful if this warning also included the specific categories that violated this.

Steps to Reproduce:

  1. Link a project with categories from multiple binaries from different compiler versions that use class properties + -ObjC
  2. Get this warning

Expected Results: The warning includes the category file name causing the issue

Actual Results: You have to binary search your pre-compiled binaries until you figure out which 2 are incompatible.

Version: ld64-351.8 (Xcode 9.4.1)

Notes: In the newest version of the ld source dumps, this warning is produced here https://github.com/michaelweiser/ld64/blob/ff67689fc5414c05cef1aa8042457738d8f9aba2/src/ld/passes/objc.cpp#L1311-L1323
