vorbis-tools 1.4.0, ogg123 and MinGW
...e wiki page
at https://wiki.xiph.org/Vorbis-tools is still pointing to 1.2.0.) I
tried compiling with MinGW ( from http://www.mingw.org ). It builds
except for the ogg123 program. Even though there's an
--enable-threads=win32 for configure, doesn't look like it does
anything.
On MinGW a pthread_t is defined as a struct not an int:
typedef struct {
void * p;
unsigned int x;
} ptw32_handle_t;
typedef ptw32_handle_t pthread_t;
The configure test to check if pthreads is available is:
int
main ()
{
pthread_t th; pthread_join(th, 0);
pthread_attr_init(0); pthread_c...

Well the intent is you should be able to set CC and LD to whatever you

[LLVMdev] adding header files to code
...s to how to introduce
header files by a transformation pass and able to use the types defined in
the header file in the pass itself.
A similar scenario can arise in a parallelizing transformation where one is
trying to create threads but this requires inclusion of pthread.h to access
the types like pthread_t. etc.

Implementing a VTable in LLVM
...vm-backend/llvm_ir_codegen/class_codegen.cc#L57:L77 <https://github.com/mukul-rathi/bolt/blob/vtable/src/llvm-backend/llvm_ir_codegen/class_codegen.cc#L57:L77>)
that generates the following global Vtable for a class Foo:
%_VtableFoo = type { void (%Foo*, i32)* }
%Foo = type { %_VtableFoo*, %pthread_t*, i32, i32, i32, i32 }
@_VtableFoo = common global %_VtableFoo { void (%Foo*, i32)* @_Foo__setgi }
The code for instantiating the table seems to generate the correct IR (create an object, store a pointer to its vtable) - https://github.com/mukul-rathi/bolt/blob/vtable/src/llvm-backend/llvm_ir_cod...
