recordDPIExportDirectives()

static void recordDPIExportDirectives ( Context &  context, const slang::ast::Scope &  scope, const slang::syntax::SyntaxNode *  syntax  )

static

Record export "DPI-C" directives in the given scope so that callable declarations can be tagged with the exported C name.

Slang resolves the directives during elaboration but does not expose them on the subroutine symbols themselves, so walk the scope's syntax to recover them.
