2011-01-14do not pass bogus $(SRC_PATH) include paths to cc during configurePaolo Bonzini3-12/+16
Non-existent -I paths are dropped silently by the compiler, but still it is not polite to pass bogus options. Configure-time tests do not need any include files from the source path, so only include -I flags at make time (when they're properly expanded).

The "test the C compiler works ok" comes before a bunch of flags are added for --cpu or just depending on the host.

According to RFC 1350 (TFTP Revision 2) the mode field can contain any combination of upper and lower case; also RFC 2349 propagates that the transfer size option ("tsize") is case in-sensitive too. Current implementation of embedded TFTP server missed that what does mess some TFTP clients. Fixed by using STRCASECMP(3) in the required places.

2011-01-10slirp: fix unaligned access in bootp codeAurelien Jarno1-15/+17
Slirp code tries to be smart an avoid data copy by using pointer to the data. This solution leads to unaligned access, in this case preq_addr, which is a 32-bit long structure. There is no real point of avoiding data copy in a such case, as the value itself is smaller or the same size as a pointer. The patch replaces pointers to the preq_addr structure by the strcture itself, and use the address 0.0.0.0 if no address has been requested (this is not a valid address in such a request). It compares it with htonl(0L) for correctness reasons, in case a code checker look for such mistakes. It also uses memcpy() for copying the data, which takes care of alignement issues. This fixes an unaligned access on IA64 host while requesting a DHCP address. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-01-10tcg/arm: improve constant loadingAurelien Jarno1-18/+21
Improve constant loading in two ways: - On all ARM versions, it's possible to load 0xffffff00 = -0x100 using the mvn rd, #0. Fix the conditions. - On <= ARMv6 versions, where movw and movt are not available, load the constants using mov and orr with rotations depending on the constant to load. This is very useful for example to load constants where the low byte is 0. This reduce the generated code size by about 7%. Also fix the coding style at the same time.

2011-01-10target-sh4: improve TLBAurelien Jarno1-21/+44
SH4 is using 16-bit instructions which means most of the constants are loaded through a constant pool at the end of the subroutine. The same memory page is therefore accessed in exec and read mode. With the current implementation, a QEMU TLB entry is set to read or read/write mode after an UTLB search and to exec mode after an ITLB search, which causes a lot of TLB exceptions to switch from read or read/write to exec and vice versa. This patch optimizes that by already setting the QEMU TLB entry in read or read/write mode when an UTLB entry is copied into ITLB (during an ITLB miss). This improve the emulation speed by about 14%.

2011-01-08tcg/arm: fix branch target change during code retranslationAurelien Jarno1-8/+20
QEMU uses code retranslation to restore the CPU state when an exception happens. For it to work the retranslation must not modify the generated code. This is what is currently implemented in ARM TCG. However on CPU that don't have icache/dcache/memory synchronised like ARM, this requirement is stronger and code retranslation must not modify the generated code "atomically", as the cache line might be flushed at any moment (interrupt, exception, task switching), even if not triggered by QEMU. The probability for this to happen is very low, and depends on cache size and associativiy, machine load, interrupts, so the symptoms are might happen randomly. This requirement is currently not followed in tcg/arm, for the load/store code, which basically has the following structure: 1) tlb access code is written 2) conditional fast path code is written 3) branch is written with a temporary target 4) slow path code is written 5) branch target is updated The cache lines corresponding to the retranslated code is not flushed after code retranslation as the generated code is supposed to be the same. However if the cache line corresponding to the branch instruction is flushed between step 3 and 5, and is not flushed again before the code is executed again, the branch target is wrong. In the guest, the symptoms are MMU page fault at a random addresses, which leads to kernel page fault or segmentation faults. The patch fixes this issue by avoiding writing the branch target until it is known, that is by writing only the branch instruction first, and later only the offset. This fixes booting linux guests on ARM hosts (tested: arm, i386, mips, mipsel, sh4, sparc). Acked-by: Edgar E. Iglesias <edgar.iglesias@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
