2009-09-11Change tests from "opt %s" to "opt < %s" so that opt doesn't see theDan Gohman
input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-08Change these tests to feed the assembly files to opt directly, insteadDan Gohman
of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-10For all RUN lines starting with "not", redirect stderr to /dev/null so testsMatthijs Kooijman
don't fail when (expected) error output is produced. This fixes 17 tests. While I was there, I also made all RUN lines of the form "not llvm-as..." a bit more consistent, they now all redirect stderr and stdout to /dev/null and use input redirect to read their input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52174 91177308-0d34-0410-b5e6-96231b3b80d8

renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51328 91177308-0d34-0410-b5e6-96231b3b80d8

providing a misleading facility. It's used once in the MIPS backend and hardcoded as "\t.globl\t" everywhere else. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-07With this patch, the LowerGC transformation becomes theGordon Henriksen
ShadowStackCollector, which additionally has reduced overhead with no sacrifice in portability. Considering a function @fun with 8 loop-local roots, ShadowStackCollector introduces the following overhead (x86): ; shadowstack prologue movl L_llvm_gc_root_chain$non_lazy_ptr, %eax movl (%eax), %ecx movl $___gc_fun, 20(%esp) movl $0, 24(%esp) movl $0, 28(%esp) movl $0, 32(%esp) movl $0, 36(%esp) movl $0, 40(%esp) movl $0, 44(%esp) movl $0, 48(%esp) movl $0, 52(%esp) movl %ecx, 16(%esp) leal 16(%esp), %ecx movl %ecx, (%eax) ; shadowstack loop overhead (none) ; shadowstack epilogue movl 48(%esp), %edx movl %edx, (%ecx) ; shadowstack metadata .align 3 ___gc_fun: # __gc_fun .long 8 .space 4 In comparison to LowerGC: ; lowergc prologue movl L_llvm_gc_root_chain$non_lazy_ptr, %eax movl (%eax), %ecx movl %ecx, 48(%esp) movl $8, 52(%esp) movl $0, 60(%esp) movl $0, 56(%esp) movl $0, 68(%esp) movl $0, 64(%esp) movl $0, 76(%esp) movl $0, 72(%esp) movl $0, 84(%esp) movl $0, 80(%esp) movl $0, 92(%esp) movl $0, 88(%esp) movl $0, 100(%esp) movl $0, 96(%esp) movl $0, 108(%esp) movl $0, 104(%esp) movl $0, 116(%esp) movl $0, 112(%esp) ; lowergc loop overhead leal 44(%esp), %eax movl %eax, 56(%esp) leal 40(%esp), %eax movl %eax, 64(%esp) leal 36(%esp), %eax movl %eax, 72(%esp) leal 32(%esp), %eax movl %eax, 80(%esp) leal 28(%esp), %eax movl %eax, 88(%esp) leal 24(%esp), %eax movl %eax, 96(%esp) leal 20(%esp), %eax movl %eax, 104(%esp) leal 16(%esp), %eax movl %eax, 112(%esp) ; lowergc epilogue movl 48(%esp), %edx movl %edx, (%ecx) ; lowergc metadata (none) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45670 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-26Tests for changes made in r45356, where IPO optimizations would dropGordon Henriksen
collector algorithms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45357 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-25GC poses hazards to the inliner. Consider:Gordon Henriksen
define void @f() { ... call i32 @g() ... } define void @g() { ... } The hazards are: - @f and @g have GC, but they differ GC. Inlining is invalid. This may never occur. - @f has no GC, but @g does. g's GC must be propagated to @f. The other scenarios are safe: - @f and @g have the same GC. - @f and @g have no GC. - @g has no GC. This patch adds inliner checks for the former two scenarios. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45351 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-25Noting and enforcing that GC intrinsics are valid only within aGordon Henriksen
function with GC. This will catch the error when the inliner inlines a function with GC into a caller with no GC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45350 91177308-0d34-0410-b5e6-96231b3b80d8

LangRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45349 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Adding a collector name attribute to Function in the IR. These Gordon Henriksen
methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44769 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-17Fix for PR1633: Verifier doesn't fully verify GC intrinsicsGordon Henriksen
LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>*, <ty>**) void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42051 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-11Make the llvm-runtest function much more amenable by eliminating all theReid Spencer
