Binary Optimization and Layout Tool - A linux command-line utility used for optimizing performance of binaries
According to the definition of IsSimple, the function whose IsSimple is false is still disassembled in relocation mode. ``` /// False if the function is too complex to reconstruct its...
I'm pretty sure them not using it is a huge missed opportunity for end users performance (billions of humans) (and related projects such as Skia, ANGLE, freetype, etc) That would...
We're running a large legacy java application with Spring and Hibernate. What could be the workarounds to make BOLT work with the jvm?

The problem I met only happens when I use `--hugify`. I have a program which works well with BOLT. > llvm-bolt ./sample -o ./sample.bolt -data=./workspace/perf.fdata -reorder-blocks=cache+ -reorder-functions=hfsort+ -split-functions=3 -split-all-cold -split-eh...
Hello I want to run a benchmark with HHVM. On the other hand, I want to apply BOLT to it as well. But I don't know what to do. ```hhvm...
In bolt/lib/Rewrite/RewriteInstance.cpp::RewriteInstance::discoverFileObjects，I find there are 2 registerName() for a symbol。 Is the first registerName redundant? ``` if (PreviousFunction && PreviousFunction->containsAddress(Address) && PreviousFunction->getAddress() != Address) { if (PreviousFunction->isSymbolValidInScope(Symbol, SymbolSize)) { if...
when using latest bolt, I receive a assert error, such as: ``` #9 0x000000000276e181 llvm::RuntimeDyldELF::resolveAArch64Relocation(llvm::SectionEntry const&, unsigned long, unsigned long, unsigned int, long) /tmp/llvm-project/llvm/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp:493:48 #10 0x00000000027705b4 llvm::RuntimeDyldELF::resolveRelocation(llvm::SectionEntry const&, unsigned long,...
When I tried to use bolt to optimize libart.so in AOSP, I used `-use-old-text` to reuse .text. A dump occurs. You can notice that the previous method is `art_quick_invoke_static_stub`. In...
