ELF: Implement the correct semantics of .[cd]tors. As I noted in the comment, the sorting order of .[cd]tors are different from .{init,fini}_array's. http://reviews.llvm.org/D17120 llvm-svn: 260620 2016-02-12 07:41:38 +08:00			`// RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t1`
Crt files are special cased by name when dealing with ctor and dtor sections, but the current code misses certain variants. In particular, those named when clang takes the code path in clang/lib/Driver/ToolChain.cpp:416, where crtfiles are named: clang_rt.<component>-<arch>-<env>.<suffix> Previously, the code only handled: clang_rt.<component>.<suffix> <component>.<suffix> This revision fixes that. 2019-10-26 02:04:56 +08:00			`// RUN: mkdir -p %t`
