.SH NAME
mono \- Mono's ECMA-CLI native code generator (Just-in-Time and Ahead-of-Time)
.SH SYNOPSIS
specified in the MONO_CONFIG environment variable, if set. See the
mono-config(5) man page for details on the format of this file.
.TP
+\fB--aot-path=PATH\fR
+List of additional directories to search for AOT images.
+.TP
\fB--debugger-agent=[options]\fR
This instructs the Mono runtime to
start a debugging agent inside the Mono runtime and connect it to a
\fBMONO_ENV_OPTIONS\fR environment variable to force all of your child
processes to use one particular kind of GC with the Mono runtime.
.TP
+\fB--gc-debug=[options]\fR
+Command line equivalent of the \fBMONO_GC_DEBUG\fR environment variable.
+.TP
+\fB--gc-params=[options]\fR
+Command line equivalent of the \fBMONO_GC_PARAMS\fR environment variable.
+.TP
\fB--arch=32\fR, \fB--arch=64\fR
(Mac OS X only): Selects the bitness of the Mono binary used, if
available. If the binary used is already for the selected bitness, nothing
Don't align stack frames on the x86 architecture. By default, Mono
aligns stack frames to 16 bytes on x86, so that local floating point
and SIMD variables can be properly aligned. This option turns off the
-alignment, which usually saves one intruction per call, but might
+alignment, which usually saves one instruction per call, but might
result in significantly lower floating point and SIMD performance.
.TP
\fB--jitmap\fR
.PP
A more powerful coverage tool is available in the module `monocov'.
See the monocov(1) man page for details.
+.SH AOT PROFILING
+You can improve startup performance by using the AOT profiler.
+.PP
+Typically the AOT compiler (\fBmono --aot\fR) will not generate code
+for generic instantiations. To solve this, you can run Mono with the
+AOT profiler to find out all the generic instantiations that are used,
+and then instructing the AOT compiler to produce code for these.
+.PP
+This command will run the specified app.exe and produce the
+\fBout.aotprof\fR file with the data describing the generic
+instantiations that are needed:
+.nf
+ $ mono --profile=aot:output=out.aotprof app.exe
+.fi
+.PP
+Once you have this data, you can pass this to Mono's AOT compiler to
+instruct it to generate code for it:
+.nf
+ $ mono --aot=profile=out.aotprof
+.fi
.SH DEBUGGING AIDS
To debug managed applications, you can use the
.B mdb
to force all of your Mono processes to use LLVM or SGEN without having
to modify any launch scripts.
.TP
-\fBMONO_ENV_OPTIONS\fR
+\fBMONO_SDB_ENV_OPTIONS\fR
Used to pass extra options to the debugger agent in the runtime, as they were passed
using --debugger-agent=.
.TP
This option allows using single-steps and breakpoints in hardware
where we cannot do it with signals.
.TP
-\fBsuspend-on-sigsegv\fR
-This option will suspend the program when a native SIGSEGV is received.
+\fBsuspend-on-native-crash\fR
+This option will suspend the program when a native crash occurs (SIGSEGV, SIGILL, ...).
This is useful for debugging crashes which do not happen under gdb,
since a live process contains more information than a core file.
.TP
+\fBsuspend-on-sigsegv\fR
+Same as \fBsuspend-on-native-crash\fR.
+.TP
\fBsuspend-on-exception\fR
This option will suspend the program when an exception occurs.
