From 4eba38ad74279b33706bc0edcb371f40c85deae1 Mon Sep 17 00:00:00 2001 From: Steve MacLean Date: Wed, 29 Apr 2020 23:49:18 -0400 Subject: [PATCH] Enable linux OOP unwinder on Windows for cross DAC Add libunwind_xdac Revise CMake files to enable compiling libunwind for UNW_REMOTE_ONLY Add minimum set of posix prototypes and constants to enable compilation Add minimum implementation of posix functions to satisfy linker. Copy freebsd-elf headers from mono include directory Cleanup comment Fix GCC constructs not supported by VC++ Use TARGET variables to configure libunwind Add PAL_VirtualUnwindOutOfProc to libunwind_xdac --- src/coreclr/CMakeLists.txt | 4 + src/coreclr/src/debug/daccess/dacfn.cpp | 12 +- src/coreclr/src/dlls/mscordac/CMakeLists.txt | 6 + .../src/pal/src/exception/remote-unwind.cpp | 75 +- .../src/pal/src/exception/seh-unwind.cpp | 59 +- .../src/pal/src/libunwind/CMakeLists.txt | 8 +- .../src/pal/src/libunwind/include/compiler.h | 8 + .../src/pal/src/libunwind/include/dwarf-eh.h | 2 +- .../src/libunwind/include/libunwind-aarch64.h | 8 + .../pal/src/libunwind/include/libunwind-arm.h | 8 + .../pal/src/libunwind/include/libunwind_i.h | 6 + .../include/tdep-aarch64/libunwind_i.h | 6 + .../libunwind/include/tdep-arm/libunwind_i.h | 6 + .../include/tdep-x86_64/libunwind_i.h | 6 + .../src/pal/src/libunwind/src/CMakeLists.txt | 141 ++- .../pal/src/libunwind/src/aarch64/Gtrace.c | 4 +- .../src/pal/src/libunwind/src/arm/Gtrace.c | 4 +- .../src/libunwind/src/cross-dac/cross-dac.c | 97 ++ .../src/libunwind/src/cross-dac/cross-dac.h | 86 ++ .../src/pal/src/libunwind/src/cross-dac/elf.h | 7 + .../pal/src/libunwind/src/cross-dac/endian.h | 7 + .../libunwind/src/cross-dac/freebsd-elf32.h | 245 +++++ .../libunwind/src/cross-dac/freebsd-elf64.h | 252 +++++ .../src/cross-dac/freebsd-elf_common.h | 865 ++++++++++++++++++ .../pal/src/libunwind/src/cross-dac/pthread.h | 7 + .../src/libunwind/src/cross-dac/sys/mman.h | 7 + .../src/libunwind/src/cross-dac/sys/syscall.h | 7 + .../libunwind/src/cross-dac/sys/ucontext.h | 7 + .../src/libunwind/src/cross-dac/ucontext.h | 7 + .../pal/src/libunwind/src/cross-dac/unistd.h | 7 + .../src/pal/src/libunwind/src/dwarf/Gexpr.c | 35 + .../pal/src/libunwind/src/mi/Gget_accessors.c | 9 + .../pal/src/libunwind/src/mi/flush_cache.c | 2 + .../src/pal/src/libunwind/src/os-linux.h | 4 +- .../pal/src/libunwind/src/x86_64/Gglobal.c | 2 +- .../src/pal/src/libunwind/src/x86_64/Gtrace.c | 4 +- 36 files changed, 1930 insertions(+), 90 deletions(-) create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/cross-dac.c create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/cross-dac.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/elf.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/endian.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/freebsd-elf32.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/freebsd-elf64.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/freebsd-elf_common.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/pthread.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/sys/mman.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/sys/syscall.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/sys/ucontext.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/ucontext.h create mode 100644 src/coreclr/src/pal/src/libunwind/src/cross-dac/unistd.h diff --git a/src/coreclr/CMakeLists.txt b/src/coreclr/CMakeLists.txt index efad61086e853d..e23898ef43319d 100644 --- a/src/coreclr/CMakeLists.txt +++ b/src/coreclr/CMakeLists.txt @@ -75,6 +75,10 @@ if(CLR_CMAKE_HOST_UNIX) add_subdirectory(src/pal) add_subdirectory(src/hosts) +else(CLR_CMAKE_HOST_UNIX) + if(CLR_CMAKE_TARGET_UNIX) + add_subdirectory(src/pal/src/libunwind) + endif(CLR_CMAKE_TARGET_UNIX) endif(CLR_CMAKE_HOST_UNIX) # Add this subdir.
