2013-10-14exec: Fix prototype of phys_mem_set_alloc and related functionsStefan Weil
phys_mem_alloc and its assigned values qemu_anon_ram_alloc and legacy_s390_alloc must have identical argument lists. legacy_s390_alloc uses the size parameter to call mmap, so size_t is good enough for all of them.

2013-10-14memory: Change MemoryRegion priorities from unsigned to signedMarcel Apfelbaum
When memory regions overlap, priority can be used to specify which of them takes priority. By making the priority values signed rather than unsigned, we make it more convenient to implement a situation where one "background" region should appear only where no other region exists: rather than having to explicitly specify a high priority for all the other regions, we can let them take the default (zero) priority and specify a negative priority for the background region.

2013-10-10tcg: Put target helper data into an array.Richard Henderson
One call inside of a loop to tcg_register_helper instead of hundreds of sequential calls. Presumably more icache and branch prediction friendly; resulting binary size mostly unchanged on x86_64, as we're trading 32-bit rip-relative references in .text for full 64-bit pointers in .rodata.

2013-09-10abitypes.h: Remove incorrect ARM ABI_LLONG_ALIGNMENTPeter Maydell
The ARM EABI specifies that 64 bit integers should be 8 aligned; remove our incorrect setting of 4 alignment. This has no actual effect since it only set the alignment for the 'abi_ullong' and 'abi_llong' types, which are used only inside code which is MIPS-specific, but it will avoid problems later if we use the types elsewhere.

2013-09-02exec: Reorganize the GETRA/GETPC macrosRichard Henderson
Always define GETRA; use __builtin_extract_return_addr, rather than having a special case for s390. Split GETPC_ADJ out of GETPC; use 2 universally, rather than having a special case for arm. Rename GETPC_LDST to GETRA_LDST to indicate that it does not contain the GETPC_ADJ value. Likewise with GETPC_EXT to GETRA_EXT. Perform the GETPC_ADJ adjustment inside helper_ret_ld/st. This will allow backends to pass along the "true" return address rather than the massaged GETPC value. In the meantime, double application of GETPC_ADJ does not hurt, since the call insn in all ISAs is at least 4 bytes long.

2013-08-29tcg-i386: Remove abort from GETPC_LDSTRichard Henderson
Indeed, remove it entirely and remove the is_tcg_gen_code check from GETPC_EXT. Fixes https://bugs.launchpad.net/qemu/+bug/1218098 wherein a call to a "normal" helper function performed a sequence of tail calls all the way into the memory helper functions, leading to a stack frame in which the memory helper function appeared to be called directly from tcg.

2013-08-26tcg-i386: Use new return-argument ld/st helpersRichard Henderson
Discontinue the jump-around-jump-to-jump scheme, trading it for a single immediate move instruction. The two extra jumps always consume 7 bytes, whereas the immediate move is either 5 or 7 bytes depending on where the code_gen_buffer gets located. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-26tcg: Tidy softmmu_template.hRichard Henderson
Avoid a loop in the tlb_fill path; the fill will either succeed or generate an exception. Inline the slow_ld/st function; it was a complete copy of the main helper except for the actual cross-page unaligned code, and the compiler was inlining it anyway. Add unlikely markers optimizing for the most common case of simple tlb miss. Make sure the compiler can optimize away the unaligned paths for a 1 byte access.

2013-08-26tcg: Add mmu helpers that take a return address argumentRichard Henderson

2013-07-23linux-user: fix segmentation fault passing with h2g(x) != xAlexander Graf
When forwarding a segmentation fault into the guest process, we were passing the host's address directly into the guest process's signal descriptor. That obviously confused the guest process, since it didn't know what to make of the (usually 32-bit truncated) address. Passing in h2g(address) makes the guest process a lot happier. To make the code more obvious, introduce a h2g_nocheck() macro that does the same as h2g(), but allows us to convert addresses that may be outside of guest mapped range into the guest's view of address space.

2013-07-22configure: Make NPTL non-optionalPeter Maydell
Now all linux-user targets support building with NPTL, we can make it mandatory. This is a good idea because: * NPTL is no longer new and experimental; it is completely standard * in practice, linux-user without NPTL is nearly useless for binaries built against non-ancient glibc * it allows us to delete the rather untested code for handling the non-NPTL configuration Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the bsd-user codebase alone. This makes no change for bsd-user, since our configure test for NPTL had a "#include <linux/futex.h>" which means bsd-user would never have been compiled with CONFIG_USE_NPTL defined, and it still is not.
