rt.arraycat Implementation of array copy support routines.
rt.cast_ Implementation of array assignment support routines.
rt.cmath2 Runtime support for complex arithmetic code generation (for Posix).
rt.config Configuration options for druntime.
rt.cover Implementation of code coverage analyzer.
rt.critical_ Implementation of support routines for synchronized blocks.
rt.deh Entry point for exception handling support routines.
rt.deh_win32 Implementation of exception handling support routines for Win32.
rt.deh_win64_posix Implementation of exception handling support routines for Win64.
rt.dmain2 Contains druntime startup and shutdown routines.
rt.dwarfeh Exception handling support for Dwarf-style portable exceptions.
rt.ehalloc Exception allocation, cloning, and release compiler support routines.
rt.lifetime This module contains all functions related to an object's lifetime: allocation, resizing, deallocation, and finalization.
rt.llmath Support for 64-bit longs.
rt.memory This module tells the garbage collector about the static data and bss segments, so the GC can scan them for roots. It does not deal with thread local static data.
rt.memset Contains a memset implementation used by compiler-generated code.
rt.minfo Written in the D programming language. Module initialization routines.
rt.monitor_ Contains the implementation for object monitors.
rt.msvc This module provides MS VC runtime helper functions that wrap differences between MS C runtime versions.
rt.msvc_math Alternate implementations of single-precision math functions missing in at least some 32-bit x86 MS VC runtime versions. These alternate symbols are referenced in the rt.msvc module.
rt.sections_android Written in the D programming language. This module provides bionic-specific support for sections.
rt.sections_darwin_64 Written in the D programming language. This module provides Darwin 64 bit specific support for sections.
rt.sections_elf_shared Written in the D programming language. This module provides ELF-specific support for sections with shared libraries.
rt.sections_osx_x86 Written in the D programming language. This module provides OS X x86 specific support for sections.
rt.sections_osx_x86_64 Written in the D programming language. This module provides OS X x86-64 specific support for sections.
rt.sections_solaris Written in the D programming language. This module provides Solaris-specific support for sections.
rt.sections_win32 Written in the D programming language. This module provides Win32-specific support for sections.
rt.sections_win64 Written in the D programming language. This module provides Win32-specific support for sections.
rt.trace Contains support code for code profiling.
rt.tracegc Contains implementations of functions called when the -profile=gc switch is thrown.
std Convenience file that allows to import entire Phobos in one import.
