[LLVMdev] Truncate float to int?
Newbie question here: what's the best way to truncate a float to a
signed int? The fptosi instruction rounds, and the fptrunc
instruction simply truncates from a large float type to a smaller
float type.

fptosi is equivalent to a C cast from float...

There aren't any LLVM passes that expect a reducible CFG at the
moment; of course, some passes are more effective with reducible CFGs.

[LLVMdev] Irreducible CFG from tail duplication
It seems that tail duplication can make a reducible CFG irreducible
(example below). Is that intentional? Are there other optimizations
that have that property?
Is irreducibility a problem for existing LLVM passes? It looks like
there was once an open project for a pass to make irreducible graphs
reducible. Was that ever implemented?

[LLVMdev] Integer typedefs for MSVC
LLVM's typedefs for int32_t etc. under MSVC (in Support/DataTypes.h)
conflict with those used by other third-party libraries. Instead of these:
#ifdef _MSC_VER
typedef __int64 int64_t;
typedef unsigned __int64 uint64_t;
typedef signed int int32_t;
typedef unsigned int uint32_t;
typedef short int16_t;
typedef unsigned short uint16_t;
typedef signed char int8_t;
typedef unsigned char uint8_t;
