introduce a new TargetLibraryInfo pass, which transformations can use to query about available library functions. For now this just has memset_pattern16, which exists on darwin, but it can be extended for a bunch of other things in the future. llvm-svn: 125965

Add support for custom names for library functions in TargetLibraryInfo. Add a custom name for fwrite and fputs on x86-32 OSX. Make SimplifyLibCalls honor the custom names for fwrite and fputs. Fixes <rdar://problem/9815881>. llvm-svn: 144876

Add more functions to the TLI. This patch adds many more functions to the target library information. All of the functions being added were discovered while doing the migration of the simplify-libcalls attribute annotation functionality to the functionattrs pass. As a part of that work the attribute annotation logic will query TLI to determine if a function should be annotated or not. Signed-off-by: Meador Inge <meadori@codesourcery.com> llvm-svn: 176514

Make MemoryBuiltins aware of TargetLibraryInfo. This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. llvm-svn: 162841

Convert sqrt functions into sqrt instructions when -ffast-math is in effect. When -ffast-math is in effect (on Linux, at least), clang defines __FINITE_MATH_ONLY__ > 0 when including <math.h>. This causes the preprocessor to include <bits/math-finite.h>, which renames the sqrt functions. For instance, "sqrt" is renamed as "__sqrt_finite". This patch adds the 3 new names in such a way that they will be treated as equivalent to their respective original names. llvm-svn: 182739

Make MemoryBuiltins aware of TargetLibraryInfo. This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. llvm-svn: 162841

Make MemoryBuiltins aware of TargetLibraryInfo. This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. llvm-svn: 162841

Disable transforms that introduce calls to exp10*() on Linux due to widespread glibc bugs. The glibc implementation of exp10 has a very serious precision bug in version 2.15 (and older versions). This is still very widely used (the current Ubuntu LTS for example uses it) and so it isn't reasonable to make transforms that produce these functions. This fixes many miscompiles introduced when we started transforming pow(10.0, ...) into exp10, and it may have fixed other latent miscompiles where exp10 provided sufficient precision but exp10f did not. This is all really horrible. The primary bug has been fixed for over a year and glibc 2.18 works correctly for the test cases I have, but it will be 2017 before the LTS using 2.15 is no longer supported by Ubuntu (and thus reasonable for folks to be relying on). =[ We're either going to need to live without these optimizations, or find a way to switch behavior more dynamically than using simply the fact that the OS is "Linux". To make matters worse, there appears to be significant testing and fixing of numerous other bugs in the exp10 family of functions right now in glibc. While those haven't been causing problems I've seen in the wild, it gives me concerns that we may need to wait until an even later release of glibc before we can reliably transform code into exp10. llvm-svn: 198093
