3.4.139 –xkeepframe[=[%all,%none,name,no%name]]

Prohibit stack related optimizations for the named functions (name).

%all

Prohibit stack related optimizations for all the code.

%none

Allow stack related optimizations for all the code.

This option is accumulative and can appear multiple times on the command line. For example, —xkeepframe=%all —xkeepframe=no%func1 indicates that the stack frame should be kept for all functions except func1. Also, —xkeepframe overrides —xregs=frameptr. For example, —xkeepframe=%all —xregs=frameptr indicates that the stack should be kept for all functions, but the optimizations for —xregs=frameptr would be ignored.

If not specified on the command line, the compiler assumes -xkeepframe=%none as the default. If specified but without a value, the compiler assumes -xkeepframe=%all
