There is no timetable.
I know the trunk version of fpc can make PE-64 files,so how long do the fpc publishs 3.3 stable version so I can use PE-64 format files as a UEFI bootable files?
But FPC already supports 64-Bit PE files for nearly twenty years already? After all it had been the first open source compiler to support Win64.
No,trunk is published in this year and only trunk supports 64-bit PE format files.
First of
trunk is the current development version and as such it's never “published”. Releases will be split of from it, but even then there is no
major release planned this year (only a minor release from the 3.2.x branch).
Second,
no not only trunk supports 64-bit PE executables, cause otherwise FPC wouldn't be able to support Windows 64 and that is already supported for nearly 20 years as I said.
What is only support in trunk is support for Windows on ARM64, but that uses the same 64-bit PE format as AMD64 does (except for the machine type field and the relocations).
