`

Parameters

format

The assembler format: intel or att

Description

The -asm compiler option sets the assembler format for inline Asm blocks when using -gen gcc.

• -gen gcc -asm intel: FB inline assembly blocks must use FB's usual Intel syntax format. Under -gen gcc, fbc will try to translate it to gcc's format automatically. For example:
• -gen gcc -asm att: FB inline assembly blocks must use gcc's format. For example:

The x86 ASM backend (-gen gas) currently only supports -asm intel and using -asm att results in an error.
