2011-04-26configure: support target dependent linkingMichael Walle1-3/+10
This patch is the first attempt to make configure more intelligent with regard to how it links to libraries. It divides the softmmu libraries into two lists, a general one and a list which depends on the target architecture.

2011-04-26configure: Make epoll_create1 test work around SPARC glibc bugPeter Maydell1-1/+9
Work around a SPARC glibc bug which caused the epoll_create1 configure test to wrongly claim that the function was present. Some versions of SPARC glibc provided the function in the library but didn't declare it in the include file; the result is that gcc warns about an implicit declaration but a link succeeds. So we reference the function as a value rather than a function call to induce a compile time error if the declaration was not present.

2011-04-26trace: Remove %s in grlib trace eventsStefan Hajnoczi4-23/+22
Trace events cannot use %s in their format strings because trace backends vary in how they can deference pointers (if at all). Recording const char * values is not meaningful if their contents are not recorded too. Change grlib trace events that rely on strings so that they communicate similar information without using strings. A follow-up patch explains this limitation and updates docs/tracing.txt.

2011-04-26linux-user: untie syscalls from UID16Riku Voipio3-17/+43
Quite a number of uid/gid related syscalls are only defined on systems with USE_UID16 defined. This is apperently based on the idea that these system calls would never be called on non-UID16 systems. Make these syscalls available for all architectures that define them. drop alpha hack to support selected UID16 syscalls. MIPS and PowerPC were also defined as UID16, to get uid/gid syscalls available, drop this error as well. Change QEMU to reflect this.

float*_scalnb() were not taking into account all cases. This patch fixes some corner cases: - NaN values in input were not properly propagated and the invalid flag not correctly raised. Use propagateFloat*NaN() for that. - NaN or infinite values in input of floatx80_scalnb() were not correctly detected due to a typo. - The sum of exponent and n could overflow, leading to strange results. Additionally having int16 defined to int make that happening for a very small range of values. Fix that by saturating n to the maximum exponent range, and using an explicit wider type if needed.
