2004-10-25Modified switch generation so that only the phi values associated with theJohn Criswell
destination basic block are copied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17212 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-20Small performance improvement in generated C code:John Criswell
Instead of unconditionally copying all phi node values into temporaries for all successor blocks, generate code that will determine what successor block will be called and then copy only those phi node values needed by the successor block. This seems to cut down namd execution time from being 8% higher than GCC to 4% higher than GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17144 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-17Print a semicolon for the unreacahble instruction. This fixes problemsChris Lattner
where C requires semicolons in some cases to indicate null statements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17107 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-17The first hunk corrects a bug when printing undef null values. We would printChris Lattner
0->field, which is illegal. Now we print ((foo*)0)->field. The second hunk is an optimization to not print undefined phi values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17094 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-20'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner
from ModulePass. Instead of implementing Pass::run, then should implement ModulePass::runOnModule. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16436 91177308-0d34-0410-b5e6-96231b3b80d8

2004-08-10Paper over CBackend/2004-08-09-va-end-null.llChris Lattner
Note that this indicates a serious problem with the way we are emitting varargs, but this should not be properly fixed until after 1.3. This patch SHOULD go into 1.3. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15602 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-25Temporarily disable this code, as it is emitting LLVM_NAN("nan") which ↵Chris Lattner
results in a call to the glibc 'nan' function because the initializer is not a string. This breaks when used in a global initializer. Try compiling this testcase for example: %X = global float <some nan value> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15223 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-02<alloca.h> on cygwin pulls in a ton of stuff (macros and function protos)Chris Lattner
that we REALLY don't want in the CBE code. With this fix, the CBE passes all of the MultiSource tests on cygwin that it does on linux. Yaay! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13975 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-28Fix the big regression that has been killing the nightly tester these lastChris Lattner
few days. Apparently the old symbol table used to auto rename collisions in the type symbol table and the new one does not. It doesn't really make sense for the new one to do so, so we just make the client do it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13877 91177308-0d34-0410-b5e6-96231b3b80d8

2004-05-20Fix to make the CBE always emit comparisons inline. Hopefully this willChris Lattner
fix the really bad code we're getting on PPC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13609 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-09syntactically loopify natural loops so that the GCC loop optimizer can find ↵Chris Lattner
them. This should *dramatically* improve the performance of CBE compiled code on targets that depend on GCC's loop optimizations (like PPC) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13438 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-27Changes to fix up the inst_iterator to pass to boost iterator checks. ThisChris Lattner
patch was graciously contributed by Vladimir Prus. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13185 91177308-0d34-0410-b5e6-96231b3b80d8

2004-02-26Fixes for PR258 and PR259.John Criswell
Functions with linkonce linkage are declared with weak linkage. Global floating point constants used to represent unprintable values (such as NaN and infinity) are declared static so that they don't interfere with other CBE generated translation units. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11884 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-24Fix some unexpected fallout from the config.h changes. Because the CBE noChris Lattner
longer was getting this #include, it always fell back on the less precise floating point initializer values, causing some testsuite failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11803 91177308-0d34-0410-b5e6-96231b3b80d8
2004-02-20It is totally unacceptable to print out (literally) millions of zeros whenChris Lattner

2004-02-15Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, someChris Lattner
hacks can be banished. Also, this gives us the opportunity to emit special code for the setjmp/longjmps which alows the elimination of one GCC warning for every setjmp/longjmp site (which is often THOUSANDS in C++ programs). Yaay! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11484 91177308-0d34-0410-b5e6-96231b3b80d8
