-a shouldn't disable optimisations at all. It just dumps the
intermediate assembly language into .s files.

*Subject:* [fpc-devel] Binary size discrepancy with -a
Hi everyone,
I've noticed something a bit weird with the Free Pascal Compiler when
you use the the -a option to dump the compiled assembly files... the
resultant binaries are sometimes smaller. I recently tried it with
Lazarus under x86_64-win64 (using "make distclean all install" with
FPCOPT):
(-O4 -OoCONSTPROP)
241,010,289 bytes - lazarus.exe
(-a -O4 -OoCONSTPROP)
235,655,062 bytes - lazarus.exe
Anyone else noticed this? Logically, shoudn't the EXE files be
completely identical?
