GCC49 by default supports plugin now? I think a gcc supplied with Linux always has linker plugin support enabled. I tried Ubuntu, and its gcc does have linker plugin support enabled. Laszlo said the RHEL version he uses has linker plugin support enabled in its gcc. For Windows, the opposite is true. I have never found a Windows gcc that has linker plugin support enabled. I had to patch the gcc build source to make it work. To Windows, the linker plugin is a dll. Binutils has the dll support code, but not gcc itself. I ported the binutils dll support to gcc. The gcc tool chains at http://sourceforge.net/projects/edk2developertoolsforwindows/ have the patch and plugin support enabled. A related problem is the need for gcc option -plugin-opt=-pass-through= when linking to a library that satisfies compiler generated calls to helper functions. This option needs the library name, and complete path if the library is not in the compiler's default library search path. For EDK2, the path depends on the build options like debug/release/noopt and gcc tool chain name. There is no simple way to create this path using the existing EDK2 build system. I have not solved this problem. Instead, I have disabled -flto for objects/libraries that trigger compiler generated helper function calls. This has essentially no impact on x86 builds, because x86 builds of most projects do not produce any compiler generated calls to helper functions. An exception is the IA32 build of AppPkg. It needs libc to resolve compiler generated calls to functions such as __umoddi3, __udivdi3, etc. The workaround is in StdLib.inc: GCC:*_GCC49LTO_IA32_CC_FLAGS = -fno-lto More exceptions are present for ARM builds. I have not enabled LTO for ARM builds because I do not know how to resolve compiler generated calls to functions such as __aeabi_dcmpeq, __aeabi_ui2d, __aeabi_dmul, etc. Thanks, Scott ]Thanks ]Feng -----Original Message----- From: Scott Duplichan [mailto:sc...@notabs.org] Sent: Wednesday, July 15, 2015 00:44 To: edk2-devel@lists.sourceforge.net Cc: Mcdaniel, Daryl Subject: [edk2] [PATCH] BaseTools: Add GCC49LTO tool chain: GCC49 with link time optimization BaseTools: Add GCC49LTO tool chain: GCC49 with link time optimization New tool chain GCC49LTO uses gcc -flto (link time optimization) for DEBUG and RELEASE builds of IA32, X64, and AARCH64. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Scott Duplichan <sc...@notabs.org> --- This patch enables gcc link time optimization by adding a stand-alone GCC49LTO tool chain. The existing GCC49 and other GCC tool chains remain unmodified. Link time optimization is added for IA32, X64 and AARCH64. ARM is omitted for the time being because I am unable to build some of the ARM projects. Link time optimization is added for RELEASE and DEBUG builds. It is not enabled for NOOPT builds because the gcc documentation states "Link-time optimization does not work well with generation of debugging information. Combining ‘-flto’ with ‘-g’ is currently experimental and expected to produce unexpected results." Builds that complete error free with GCC49 also complete with GCC49LTO. However, use of -flto allows gcc to see and warn about an AutoGen.h/ AutoGen.c declaration difference for PCD array data. Other warnings are exposed when ASSERT code is expanded and optimized. A separate patch that allows overriding the warning as error option lets the builds complete so that -flto can be tested before the autogen and other warning issues are resolved. The only successful boot test so far is Duet. The patches from last year are still needed. I may rebsubmit these patches. GCC builds using the latest CorebootPayloadPkg code are not working on my board, so this needs to be debugged before it can be used as a gcc -flto test case. While this patch mainly targets BaseTools, some non-BaseTools files are changed: ArmVirt.dsc.inc and ArmVExpress.dsc.inc are modified to add GCC LTO compatibility to their overrides of DLINK_FLAGS. StdLib.inc is modified to disable link time optimization for its build. This is because gcc code generation for StdLib contains calls to compiler helper functions. While this can work with link time optimization, it requires linker option -plugin-opt=-pass-through=. Right now we have no easy way to generate the library path needed by -plugin-opt=-pass-through=. Laszlo suggested adding link time optimization support for GCC48 since it ships with RHEL-7.1. I will do that in a day or two. I want to submit this patch now because I have done a lot of build testing with it.
