[#llvm-handleExecNameEncodedBEOpts]
= xref:llvm.adoc[llvm]::handleExecNameEncodedBEOpts
:relfileprefix: ../
:mrdocs:

Handle backend options that are encoded in the executable name.

== Synopsis

Declared in `<llvm/FuzzMutate/FuzzerCLI.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
handleExecNameEncodedBEOpts(xref:llvm/StringRef.adoc[StringRef] ExecName);
----

== Description

Parses some common backend options out of a specially crafted executable name (argv[0]). For example, a name like llvm‐foo‐fuzzer‐‐aarch64‐gisel might set up an AArch64 triple and the Global ISel selector. This should be called _before_ parseFuzzerCLOpts if calling both.

This is meant to be used for environments like OSS‐Fuzz that aren't capable of passing in command line arguments in the normal way.

== Parameters

[cols="1,4"]

| Name| Description
| *ExecName*
