Something along these lines is absolutely sorely lacking in FPC
currently, don't let anyone tell you otherwise.
How is it better than intrinsics support (similiar to gcc/icc etc.)?
Intrinsics are common, and prepared for you by compiler devels.
Inline assembler blocks are something you use as a programmer as soon
as you reuse a block a lot. An example in the embedded world, e.g. as an
interrupt prologue or epilogue, things like prologues for SPI operations
(lowering/raising CS and enabling/disabling interrupts, padded with
appropriate nops if needed if the slave is slower than the master).
Example PIC32MK/MZ (=MIPS) which has quite some different interrupt
prologues depending on what features are used (shadow registers and the
like).
These are now gcc inline macros.
