[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

...t'll be leaked now.
However, in 'Lexer.l', you have the following code:
<<EOF>> {
/* Make sure to free the internal buffers for flex when we are
* done reading our input!
*/
yy_delete_buffer(YY_CURRENT_BUFFER);
return EOF;
}
Which should take care of it.

[PATCH 0/9] libxl: disk configuration handling
This is v3 of my disk series. What were previously patches 01-06 have
been applied. These are the tested and updated remainder, addressing
the previous comments.
1 Preparatory work.
2-4 The new parser and its documentation.
5-6 Replace old parsers with calls to the new one.
7-8 Two features, one of them essential.
9 Basic test suite for disk string parsing, as adhoc script.

Ok, that makes sense.
