This option generates a report written to standard output on the inlining of functions by the compiler. The type of report depends on the value of n, which must be 0, 1, or 2.
No report is generated.
A summary report of default values of inlining parameters is generated.
A detailed report of inlining messages is generated, showing which callsites are inlined and which are not, with a short reason for not inlining a callsite. In some cases, this report will include suggested values for -xinline_param that can be used to inline a callsite that is not inlined.
When -xinline_report is not specified, the default value for n is 0. When -xinline_report is specified without =n, the default value is 1.
When -xlinkopt is present, the inlining messages about the callsites that are not inlined might not be accurate.
The report is limited to inlining performed by the compiler that is subject to the heuristics controllable by the -xinline_param option. Callsites inlined by the compiler for other reasons may not be reported.
