IFX compiler makes a futile attempt to assemble

[mecej4]

When the ifx compiler driver is asked to produce assembly output with the /Fa option, after producing a GNU assembler format file it seems to attempt to assemble the file just produced but as if it were in MASM format.

From years of using ifort, we expect that the output assembly file is meant only for inspection and rarely suitable for assembling. The driver was not given any input assembly files, so it should not be attempting conversion to .OBJ files.

A related thread from about two years ago:

The remedy for this and the other thread you point to is in its final stages. Look for it in a release later this year. 

[mecej4]

Thanks, that is good to know.

Is this fixed now? Related question: is there somewhere we can look for more detailed release notes for each version (bug fixes, etc.)?

As reported in the thread that @mecej4 noted above. Yes.

I just tested ifx 2024.0.0 and it works.

ifx: command line remark #10439: option '/Fa' creates an assembly file but not an object file.

>> is there somewhere we can look for more detailed release notes for each version (bug fixes, etc.)?

No, we don't publish a list of bug fixes. I argue against it because often the subject lines are just too cryptic for the reader to decide if the bug is related to their issue.

We do make the effort to post on the original thread when a bug is fixed along with the compiler version.
