Example 1 with CSourceCodeWriter

use of com.oracle.svm.hosted.c.codegen.CSourceCodeWriter in project graal by oracle.

the class NativeBootImage method writeHeaderFile.

void writeHeaderFile(Path outFile, String imageName, boolean dynamic) {
    List<HostedMethod> methodsWithHeader = uniqueEntryPoints.stream().filter(this::shouldWriteHeader).collect(Collectors.toList());
    methodsWithHeader.sort(NativeBootImage::sortMethodsByFileNameAndPosition);
    if (methodsWithHeader.size() > 0) {
        CSourceCodeWriter writer = new CSourceCodeWriter(outFile.getParent());
        String imageHeaderGuard = "__" + imageName.toUpperCase().replaceAll("[^A-Z0-9]", "_") + "_H";
        writer.appendln("#ifndef " + imageHeaderGuard);
        writer.appendln("#define " + imageHeaderGuard);
        String preamblePath = NativeImageOptions.PreamblePath.getValue();
        if (preamblePath != null) {
            NativeImageHeaderPreamble.read(preamblePath).forEach(writer::appendln);
        } else {
            writer.appendln("#include <" + DEFAULT_HEADER_FILE_NAME + ">");
        }
        if (NativeImageOptions.getCStandard() != CStandards.C89) {
            writer.appendln("#include <stdbool.h>");
        }
        writer.appendln("#if defined(__cplusplus)");
        writer.appendln("extern \"C\" {");
        writer.appendln("#endif");
        methodsWithHeader.forEach(m -> writeMethodHeader(m, writer, dynamic));
        writer.appendln("#if defined(__cplusplus)");
        writer.appendln("}");
        writer.appendln("#endif");
        writer.appendln("#endif");
        writer.writeFile(outFile.getFileName().toString(), false);
    }
}
