The newlib C library provides iprintf(), a restricted version of printf without support for floating-point formatting. I'd like to add an optimization which turns calls to printf() into calls to iprintf() if the format string has no floating point specifiers. At the moment I've got this working locally by adding code to the...

This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

Well, I'm porting Cygnus' newlib libc to the COM32 environment, and got it to printf() Hello, World! yesterday. The binary was 24K; 14K if I used iprintf() [printf sans floating-point support] instead of printf(). There is still a lot of work to do, obviously, but I was rather excited over having gotten it this far :) This should make it a lot easier to support all kinds of odd UI support for SYSLINUX, for those that want it. -hpa

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its
