[Qemu-devel] Questions/comments on TCG

2008-03-07 Thread Stuart Brady
Hi, I have a few questions regarding TCG which I'd like to ask, and also a few minor comments. I've made a start on a PA-RISC (HPPA) TCG target, but there are a few things that I'm not sure of. Before I ask, I should make it clear that I do understand that the current SPARC TCG code is

[Qemu-devel] [PATCH] some functions declared () rather than (void)

2008-03-07 Thread Ian Jackson
There are a few functions which are declared using this syntax return_value function() when in fact they take no arguments and so should be return_value function(void) The former is either a pre-ANSI declaration with unspecified argument types (which is usually inappropriate), or a mistake by

[Qemu-devel] [PATCH] Remove blank elements in tcg_target_reg_alloc_order[]

2008-03-07 Thread Stuart Brady
Hi, tcg_target_reg_alloc_order[] contains blank elements, which default to TCG_REG_EAX/TCG_REG_RAX on i386/x86_64, and TCG_REG_G0 on SPARC. The included patch removes these elements, and adds an ARRAY_SIZE macro to osdep.h, which is then used to check the size of the array. I'm not sure if the
