Title: assembly output.
Post by: sergioantonio2013 on January 05, 2014, 01:17:42 pm

How do I get lazarus to compile to assembly code or to save the assembly code to a file when compiling a program.

I want to optimize by hand some code using mmx, and I want to see the assembly code generated by the freepascal compiler. Any help?

Thanks

Don't understand what do you want to do, but If related, you can use ASM code in your projects.

He wants to output the generated assembler source, i.e. not the (linked) binary/machine code.

This is possible, don't know if

Code: [Select]

fpc -h
gives enough info on this, but it should be a switch in fpc.exe

I remember some threads in the forum or perhaps the FPC mailing lists about this; you'd have to search
