From: Eric Christopher Date: Mon, 2 Apr 2018 23:17:55 +0000 (+0000) Subject: Remove llvm-mcmarkup. X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=84e2cd6c021a1564e77c2f099f9d3a3c21906e90;p=platform%2Fupstream%2Fllvm.git Remove llvm-mcmarkup. It was never used and I've checked with the original authors. llvm-svn: 329029 --- diff --git a/llvm/test/CMakeLists.txt b/llvm/test/CMakeLists.txt index 5a97677..457509c 100644 --- a/llvm/test/CMakeLists.txt +++ b/llvm/test/CMakeLists.txt @@ -67,7 +67,6 @@ set(LLVM_TEST_DEPENDS llvm-lto2 llvm-mc llvm-mca - llvm-mcmarkup llvm-modextract llvm-mt llvm-nm diff --git a/llvm/test/MC/Markup/basic-markup.mc b/llvm/test/MC/Markup/basic-markup.mc deleted file mode 100644 index 2fa5ebb..0000000 --- a/llvm/test/MC/Markup/basic-markup.mc +++ /dev/null @@ -1,16 +0,0 @@ -// RUN: llvm-mcmarkup %s | FileCheck %s - - push {, , } - sub , - ldr , , ]> - - -// CHECK: reg -// CHECK: reg -// CHECK: reg -// CHECK: reg -// CHECK: imm -// CHECK: reg -// CHECK: mem -// CHECK: reg -// CHECK: imm diff --git a/llvm/test/MC/Markup/lit.local.cfg b/llvm/test/MC/Markup/lit.local.cfg deleted file mode 100644 index ab28eed..0000000 --- a/llvm/test/MC/Markup/lit.local.cfg +++ /dev/null @@ -1,2 +0,0 @@ -config.suffixes = ['.mc'] - diff --git a/llvm/test/lit.cfg.py b/llvm/test/lit.cfg.py index 4c01992..2c63e84 100644 --- a/llvm/test/lit.cfg.py +++ b/llvm/test/lit.cfg.py @@ -141,7 +141,7 @@ tools.extend([ 'dsymutil', 'lli', 'lli-child-target', 'llvm-ar', 'llvm-as', 'llvm-bcanalyzer', 'llvm-config', 'llvm-cov', 'llvm-cxxdump', 'llvm-cvtres', 'llvm-diff', 'llvm-dis', 'llvm-dwarfdump', 'llvm-extract', 'llvm-isel-fuzzer', 'llvm-opt-fuzzer', 'llvm-lib', - 'llvm-link', 'llvm-lto', 'llvm-lto2', 'llvm-mc', 'llvm-mca','llvm-mcmarkup', + 'llvm-link', 'llvm-lto', 'llvm-lto2', 'llvm-mc', 'llvm-mca', 'llvm-modextract', 'llvm-nm', 'llvm-objcopy', 'llvm-objdump', 'llvm-pdbutil', 'llvm-profdata', 'llvm-ranlib', 'llvm-readobj', 'llvm-rtdyld', 'llvm-size', 'llvm-split', 'llvm-strings', 'llvm-tblgen', diff --git a/llvm/tools/LLVMBuild.txt b/llvm/tools/LLVMBuild.txt index fca089c..8fe289c 100644 --- a/llvm/tools/LLVMBuild.txt +++ b/llvm/tools/LLVMBuild.txt @@ -38,7 +38,6 @@ subdirectories = llvm-lto llvm-mc llvm-mca - llvm-mcmarkup llvm-modextract llvm-mt llvm-nm diff --git a/llvm/tools/llvm-mcmarkup/CMakeLists.txt b/llvm/tools/llvm-mcmarkup/CMakeLists.txt deleted file mode 100644 index 0a51e99f..0000000 --- a/llvm/tools/llvm-mcmarkup/CMakeLists.txt +++ /dev/null @@ -1,5 +0,0 @@ -set(LLVM_LINK_COMPONENTS support) - -add_llvm_tool(llvm-mcmarkup - llvm-mcmarkup.cpp - ) diff --git a/llvm/tools/llvm-mcmarkup/LLVMBuild.txt b/llvm/tools/llvm-mcmarkup/LLVMBuild.txt deleted file mode 100644 index 6423493..0000000 --- a/llvm/tools/llvm-mcmarkup/LLVMBuild.txt +++ /dev/null @@ -1,22 +0,0 @@ -;===- ./tools/llvm-mcmarkup/LLVMBuild.txt ----------------------*- Conf -*--===; -; -; The LLVM Compiler Infrastructure -; -; This file is distributed under the University of Illinois Open Source -; License.
