2011-01-14target-sh4: add fipr instructionAurelien Jarno3-0/+33
Add the fipr FVm,FVn instruction, which computes the inner products of a 4-dimensional single precision floating-point vector. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14target-sh4: implement FPU exceptionsAurelien Jarno1-22/+136
FPU exception support where not implemented on SH4. Implement them by clearing the softfloat exceptions flags before an FP instruction (the SH4 FPU also clear them before an instruction), and calling a function to update the FPSCR register after an FP instruction. This function update the corresponding FPSCR bits (both flags and cumulative flags) and trigger exception if enabled. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14target-sh4: implement flush-to-zeroAurelien Jarno2-0/+2
When the FPSCR.DN bit is set, the SH4 FPU treat denormalized numbers as zero. Enable the corresponding softfloat option when this bit is set. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14target-sh4: define FPSCR constantsAurelien Jarno3-9/+37
Define FPSCR constants for all field and use them instead of hardcoded values. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14target-sh4: use default-NaN modeAurelien Jarno1-0/+1
SH4 FPU doesn't propagate NaN, and instead always regenerate new ones. Enable the default-NaN mode by default. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14softfloat: fix default-NaN modeAurelien Jarno1-18/+18
When the default-NaN mode is enabled, it should return the default NaN value, but it should anyway raise the invalid operation flag if one of the operand is an sNaN. I have checked that this behavior matches the ARM and SH4 manuals, as well as real SH4 hardware.

2011-01-14target-sh4: switch sh4 to softfloatAurelien Jarno1-3/+3
We need to be able to catch exceptions correctly and thus enable softfloat on SH4. As all machines except i386 and x86_64 are using softfloat, make it the default and change the case to detect i386 and x86_64. Note that CRIS doesn't have an FPU, so it can be configured with both softfloat-native and softfloat. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-14configure: fix broken testAurelien Jarno1-1/+1
Since commit d1807a4f836c27f6dc7061e53a834dd27f78e46a ./configure tries to test files and directories with "test -f", which only test for regular files. Test with "test -e", which looks for any kind of files. This unbreak the configure script when not using a separate object directory. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

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).

2011-01-13slirp: Use strcasecmp() to check tftp mode, tsizeSergei Gavrikov1-2/+2
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.
