@llvm/pr-subscribers-clang-driver @llvm/pr-subscribers-mlir Author: Tarun Prabhu (tarunprabhu) ChangesAdd support for the -frecord-command-line option that will produce the llvm.commandline metadata which will eventually be saved in the object file. This behavior is also supported in clang. Some refactoring of the code in flang to handle these command line options was carried out. The corresponding -grecord-command-line option which saves the command line in the debug information has not yet been enabled for flang. Notes for reviewers: In #98517, the This required a change to If others have better suggestions for how to handle this, I am happy to make changes. Patch is 28.39 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/102975.diff 24 Files Affected:

Do you know whether flang's flow is affected by f_clang_Group?
There was a problem hiding this comment.
Could you clarify what you mean by "flang's flow"?
I don't know exactly what f_clang_Group does. I haven't been able to determine what effect it has on things like help messages. For instance -frecord-command-line does not appear in either clang --help, or clang --help-hidden.

There was a problem hiding this comment.
I mean't whether f_clang_Group is processed by flang or not. I see that this is used by some other commands as well. So it is alrite.
There was a problem hiding this comment.
I think f_clang_Group is a legacy group for Clang options not in GCC. f_clang_Group has never gain significant adoption and it's used by any code.
New -f options can just use f_Group.
There was a problem hiding this comment.
I have changed the group to f_Group since that does not suggest that the options are exclusive to clang.

Add support for the -frecord-command-line option that will produce the llvm.commandline metadata which will eventually be saved in the object file. This behavior is also supported in clang. Some refactoring of the code in flang to handle these command line options was carried out. The corresponding -grecord-command-line option which saves the command line in the debug information has not yet been enabled for flang.
…the code to CommonArgs instead. That code has been put in the clang::driver namespace.
…uggest that the options are "clang only"

I've had to revert this due to the failures listed above. To reproduce, configure with (the other 2 bots are not called shared libs but they do enable this setting too) This happens to at least the bbc and tco tools that I notice include a .inc file related to commands. So that might be the issue, but simply removing the include wasn't correct so I leave it to you to figure out. |

Add support for the -frecord-command-line option that will produce the llvm.commandline metadata which will eventually be saved in the object file. This behavior is also supported in clang. Some refactoring of the code in flang to handle these command line options was carried out. The corresponding -grecord-command-line option which saves the command line in the debug information has not yet been enabled for flang.
Notes for reviewers: In #98517, the
tune-cpuargument was added to the constructor of the lowering bridge object in flang. This PR would have required adding another option to it. It is possible more such arguments may be added in the future. To avoid having to add new arguments each time, theTargetOptionsandCodeGenOptionsobjects from the frontend are now passed directly through to the lowering bridge constructor.This required a change to
bbcwhere emptyTargetOptionsandCodeGenOptionsobjects had to be created.If others have better suggestions for how to handle this, I am happy to make changes.
