IPF-fp-speculation, QIPF-fp-speculation

Tells the compiler the mode in which to speculate on floating-point (FP) operations. This is a deprecated option.

IDE Equivalent

Windows: None

Linux: Floating Point > Floating-Point Speculation

Mac OS: None

Architectures

IA-64 architecture

Syntax

Linux:	-IPF-fp-speculationmode
Mac OS:	None
Windows:	/QIPF-fp-speculationmode

Arguments

mode	Is the mode for floating-point operations. Possible values are:
	fast	Tells the compiler to speculate on floating-point operations.
	safe	Tells the compiler to disable speculation if there is a possibility that the speculation may cause a floating-point exception.
	strict	Tells the compiler to disable speculation on floating-point operations.
	off	Same as strict.

Default

-IPF-fp-speculationfast or
/QIPF-fp-speculationfast

The compiler speculates on floating-point operations when optimizations are enabled. If you specify no optimizations (-O0 on Linux; /Od on Windows), the default is -IPF-fp-speculationsafe (Linux) or /QIPF-fp-speculationsafe (Windows).

Description

This option tells the compiler the mode in which to speculate on floating-point (FP) operations.
