It builds a set of static libraries and installs them into the CLANG/LLVM toolchain resource folder. The compiler-rt fuzzer and address sanitizer tools require additional LLVM binary tools installed to allow stack trace decoding actively during executable analysis. This patch conditionally enables these tools. https://github.com/google/sanitizers/wiki/AddressSanitizerCallStack Signed-off-by: Matthew Weber Cc: Romain Naour Cc: Ricardo Martincoski Cc: Valentin Korenblit Cc: Michael Drake --- Changes v1 -> v2 [Romain - Removed unnecessary host-cmake dependency v2 -> v3 [Romain - Update to use COMPILER_RT_INSTALL_PATH for library install [Ricardo - Fixed check-package extra line - Spelling in commit message v3 -> v4 [Valentin - Pointed out that non-glibc libraries won't build. Further investigation shows that the lib asan support in compiler-rt doesn't have the libc checks yet to support multiple libraries. (https://patchwork.ozlabs.org/patch/339938/ was the best example I could find and it doesn't look like anything has changed in the recent codebase) v4 -> v5 [Thomas P - Revisited staging install step and found a cleaner way to use the default and then a hook to setup the runtime library path v6 - Bumped to 7.0.1 to match current LLVM/Clang version v7 - Rebased on master for 8.0 LLVM/Clang version - Added comment about bumping verions of LLVM/Clang and Compiler-rt together [Romain - Disabled test cases (-DCOMPILER_RT_INCLUDE_TESTS=OFF) v8 - Rebased and updated version to 9.x to match llvm/clang [Romain - Squashed "[v7,1/5]package/llvm: install target binary/debug tools" to be included in this patch [Michael D - compiler-rt symlink creation to include shared folder such that control flow lists work --- DEVELOPERS | 1 + package/Config.in | 1 + package/compiler-rt/Config.in | 14 +++++++++++ package/compiler-rt/compiler-rt.hash | 3 +++ package/compiler-rt/compiler-rt.mk | 37 ++++++++++++++++++++++++++++ package/llvm/llvm.mk | 11 ++++++++- 6 files changed, 66 insertions(+), 1 deletion(-) create mode 100644 package/compiler-rt/Config.in create mode 100644 package/compiler-rt/compiler-rt.hash create mode 100644 package/compiler-rt/compiler-rt.mk diff --git a/DEVELOPERS b/DEVELOPERS index db7d81fa86..e9cf60c1cd 100644 --- a/DEVELOPERS +++ b/DEVELOPERS @@ -1522,6 +1522,7 @@ F: package/bridge-utils/ F: package/checkpolicy/ F: package/checksec/ F: package/cgroupfs-mount/ +F: package/compiler-rt/ F: package/crda/ F: package/cunit/ F: package/dacapo/ diff --git a/package/Config.in b/package/Config.in index d4cfd50a4b..9d3ac0d5c2 100644 --- a/package/Config.in +++ b/package/Config.in @@ -1700,6 +1700,7 @@ menu "Other" source "package/clapack/Config.in" source "package/classpath/Config.in" source "package/cmocka/Config.in" + source "package/compiler-rt/Config.in" source "package/cppcms/Config.in" source "package/cracklib/Config.in" source "package/dawgdic/Config.in" diff --git a/package/compiler-rt/Config.in b/package/compiler-rt/Config.in new file mode 100644 index 0000000000..9afc0d9d60 --- /dev/null +++ b/package/compiler-rt/Config.in @@ -0,0 +1,14 @@ +config BR2_PACKAGE_COMPILER_RT + bool "compiler-rt" + depends on BR2_PACKAGE_LLVM + depends on BR2_TOOLCHAIN_USES_GLIBC # asan lib requires + help + A collection of runtime libraries primarily used by clang and + llvm to provide builtins, sanitizer runtimes, and profiling + at runtime. + + https://compiler-rt.llvm.org/ + +comment "compiler-rt requires llvm to be enabled and a glibc toolchain" + depends on !BR2_PACKAGE_LLVM + depends on !BR2_TOOLCHAIN_USES_GLIBC diff --git a/package/compiler-rt/compiler-rt.hash b/package/compiler-rt/compiler-rt.hash new file mode 100644 index 0000000000..cf2f1890ad --- /dev/null +++ b/package/compiler-rt/compiler-rt.hash @@ -0,0 +1,3 @@ +# Locally computed: +sha256 56e4cd96dd1d8c346b07b4d6b255f976570c6f2389697347a6c3dcb9e820d10e compiler-rt-9.0.0.src.tar.xz +sha256 dd27f8c290bcdc8368549cd7cd98710a9dbdc34122f2e096a1edb97824ed4148 LICENSE.TXT diff --git a/package/compiler-rt/compiler-rt.mk b/package/compiler-rt/compiler-rt.mk new file mode 100644 index 0000000000..3d2cbcbff5 --- /dev/null +++ b/package/compiler-rt/compiler-rt.mk @@ -0,0 +1,37 @@ +################################################################################ +# +# compiler-rt +# +################################################################################ + +# Compiler-RT should be bumped together with LLVM and Clang as the run-time is +# tied to the version of those tools +COMPILER_RT_VERSION = 9.0.0 +COMPILER_RT_SOURCE = compiler-rt-$(COMPILER_RT_VERSION).src.tar.xz +COMPILER_RT_SITE = http://llvm.org/releases/$(COMPILER_RT_VERSION) +COMPILER_RT_LICENSE = NCSA MIT +COMPILER_RT_LICENSE_FILES = LICENSE.TXT +COMPILER_RT_DEPENDENCIES = host-clang llvm + +COMPILER_RT_INSTALL_STAGING = YES +COMPILER_RT_INSTALL_TARGET = NO + +COMPILER_RT_CONF_OPTS=-DCOMPILER_RT_STANDALONE_BUILD=OFF \ + -DCOMPILER_RT_STANDALONE_BUILD=ON \ + -DCOMPILER_RT_DEFAULT_TARGET_TRIPLE=$(GNU_TARGET_NAME) \ + -DLLVM_CONFIG_PATH=$(HOST_DIR)/usr/bin/llvm-config + +# The installation of the target runtime libraries defaults to DESTDIR, however +# host-clang resources directory needs a link so Clang can find the runtime +# libraries in the same location they would be if built as part of the Clang +# build.
