Examples with LinkerInvocation com.oracle.svm.core.LinkerInvocation used on opensource projects

Example 1 with LinkerInvocation

use of com.oracle.svm.core.LinkerInvocation in project graal by oracle.

the class ExecutableViaCCBootImage method getLinkerInvocation.

@Override
LinkerInvocation getLinkerInvocation(Path outputDirectory, Path tempDirectory, String imageName) {
    String mainSymbolNameStem = NativeBootImage.globalSymbolNameForMethod(mainEntryPoint);
    // HACK: guess main symbol name using hacked-up knowledge of object file format
    String mainSymbolAlias = (ObjectFile.getNativeFormat() == ObjectFile.Format.MACH_O) ? "_main" : "main";
    String mainSymbolName = (ObjectFile.getNativeFormat() == ObjectFile.Format.MACH_O) ? "_" + mainSymbolNameStem : mainSymbolNameStem;
    LinkerInvocation inv = super.getLinkerInvocation(outputDirectory, tempDirectory, imageName);
    inv.addSymbolAlias(mainSymbolAlias, mainSymbolName);
    return inv;
}

Example 2 with LinkerInvocation

use of com.oracle.svm.core.LinkerInvocation in project graal by oracle.

the class NativeBootImageViaCC method write.

@Override

    String cmdstr = "";
    String outputstr = "";
    try (Indent indent = debug.logAndIndent("Writing native image")) {

        write(tempDirectory.resolve(imageName + ObjectFile.getFilenameSuffix()));
        // 2. run a command to make an executable of it
        int status;

                 * multiple runs. It actually doesn't matter, because it's a .a file which will get
                 * absorbed into the executable, but avoiding clobbering will help debugging.
