[LLVMdev] Apparent optimizer bug on X86_64
Compiling a simple automaton created by GNU bison with -O1 or -O2
resulted in the following machine code:
1300 /*-----------------------------.
1301 | yyreduce -- Do a reduction. |
1302 `-----------------------------*/
1303 yyreduce:
1304 /* yyn is the number of a rule to reduce with. */
1305 yylen = yyr2[yyn];

[LLVMdev] problem trying to write an LLVM register-allocation pass
I have a new problem: Register RBP is used in a function foo. (I am not
allocating RBP to any virtual register, the instances of RBP in function
foo are in the machine code when my register allocator starts.)
Function foo calls function bar. Register RBP is not saved across the
call, though it is live after the call. Function bar includes a virtual
register. The code that I'm using to
