global-hoist, Qglobal-hoist

Enables certain optimizations that can move memory loads to a point earlier in the program execution than where they appear in the source.

Syntax

Linux:
-global-hoist
-no-global-hoist
macOS:
-global-hoist

Windows:
/Qglobal-hoist

Arguments
None
Default
-global-hoist
or
/Qglobal-hoist
Certain optimizations are enabled that can move memory loads.
Description
This option enables certain optimizations that can move memory loads to a point earlier in the program execution than where they appear in the source. In most cases, these optimizations are safe and can improve performance.
The negative form of the option is useful for some applications, such as those that use shared or dynamically mapped memory, which can fail if a load is moved too early in the execution stream (for example, before the memory is mapped).
Alternate Options
None
