Hi.
I want to know if there is a way to exclude a particular optimization at a particular optimization level in FPC.
Background
I was working on a particular codebase of mine in FPC 320 Fixes and I discovered an issue with a particular optimization, USELOADMODIFYSTORE to be precise.
When this particular optimization is enabled, it tends to slow down my code by a particular factor and at worse produce incorrect results when used in combination with other processor specific optimization like -CpCoreAVX2 and -OpCoreAVX2.
Now the problem here is that this particular optimization USELOADMODIFYSTORE is enabled by default in -O3 level optimization.
So back to my question, is there any way to exclude this particular optimization at this level other than having to use a lower optimization level, say -O2 and manually add other specific optimizations I want to maybe an .inc or my source file?
