LLILUM Compiler Frontend

Front End Configuration

The compiler tool in the Zelig system is located at the FrontEnd project.

A typical configuration file for the compiler looks like a list of instructions, path and assembly references. This is the configuration file for the LLVM Demo for LPC1768 Mbed dev board named mbed_simple.FrontEndConfig:

###
### Location of the Zelig assemblies.
###
-HostAssemblyDir   ..\..\..\..\ZeligBuild\Host\bin\Debug
-DeviceAssemblyDir ..\..\..\..\ZeligBuild\Target\bin\Debug

-CompilationSetup Microsoft.Zelig.Configuration.Environment.LPC1768MBEDHostedCompilationSetup
#-CompilationSetup Microsoft.Zelig.Configuration.Environment.K64FMBEDHostedCompilationSetup


###
### We need to include this assembly to get the right drivers.
###
-Reference Microsoft.CortexM3OnMBED
-Reference Microsoft.CortexM3OnCMSISCore
-Reference Microsoft.DeviceModels.ModelForCortexM3
-Reference LPC1768

#-Reference Microsoft.CortexM4OnMBED
#-Reference Microsoft.CortexM4OnCMSISCore
#-Reference Microsoft.DeviceModels.ModelForCortexM4
#-Reference K64F

Keywords

• #: marks the start of a comment line
• -Reference <assembly>: Instruct Zelig to load _assembly _as a reference for the application. This includes device drivers as well as system assemblies.
• -HostAssemblyDir <directory>: location of assemblies to be used for by the compiler, e.g. for loading phases or code transformations.
• -DeviceAssemblyDir <directory>: location of assemblies to be used for by the compiler, e.g. for loading phases or code transformations.
• -CompilationPhaseDisabled <phase>: instructs the compiler to skip the phase phase.
• -OutputName <name>: output image name
• -OutputDir <dir>: output directory
• -DumpIR: instructs the compiler to dump the IR after generating the image
• -DumpIRpre: instructs the compiler to dump the IR before applying any code transformation
• -DumpIRpost: instructs the compiler to dump the IR after applying all transformations, inclusive of the full TS
• -DumpLLVMIR: instructs the compiler to dump the IR after applying all transformations
• -ReloadState: instructs the compiler to reload the last persisted IR. Useful to debug and develop LLVM IR translation.
• -DumpLLVMIR_TextRepresentation: instructs the compiler to dump the LLVM IR in readable format.
• -MaxProcs <n>: instructs the compiler to use n threads to compile
