[BZ #13983] Let not confuse the user and think there's an error instead of a warning.
2012-05-08Minor optimization to sparc VIS3 floor() implementation.David S. Miller2-2/+4
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_floor-vis3.S: Use movxtod instead of popping the value on the stack.

2012-05-08ARM: Define HAVE_ARM_PCS_VFP in config.h.Carlos O'Donell2-0/+7
If the compiler and flags would select the hard-float ABI then the ARM configure fragment will set HAVE_ARM_PCS_VFP. This is later used by the ARM shlib-versions to select the appropriately named dynamic linker.

2012-05-08Revert "Revert "Build glibc with -frounding-math""Andreas Jaeger2-1/+14

2012-05-08tftp.h: rework layout to work with fortificationMike Frysinger2-9/+28
The current tftp structure does not work when fortification is enabled. Starting with gcc-4.5, more size checking was added to trigger these. Older versions just didn't have enough information, so they returned -1 as the sizes. First, the tu_stuff field is declared as 1 byte (when it's really an arbitrary length C string), so attempting to strcpy() with it results in crashes. This fails with _FORTIFY_SOURCE=1. Second, even if we change that to [0] (since gcc does not allow flexible array members in an union), gcc is not smart enough to see that they are two overlapping flexible arrays (tu_stuff and tu_data), so it will still trigger an abort with _FORTIFY_SOURCE=2. This is because it thinks that tu_stuff is 0 bytes and tu_data comes after it. Talking to upstream gcc, they don't seem terribly inclined to fix the 2nd issue, but even if they did, we still have plenty of 4.5 and 4.6 installs that would hit problems. So, let's re-order with a few more anonymous structs & unions so that the fields are laid out with a zero-length array always as the last field. This seems to fix things with gcc-4.6, and the tftp-hpa pkg continues to build & work.

2012-05-03Fix tst-obprintf - and mcheck in generalAndreas Jaeger2-0/+12
tst-obprintf failed with GCC 4.7. It turned out that this is the fault of GCC optimizing away the following from malloc/mcheck.c: /* We call malloc() once here to ensure it is initialized. */ void *p = malloc (0); free (p); gcc sees the malloc(0);free pair and removes it completely. And now malloc is not properly initialized and we screw up if both mcheck is used (via tst-obprintf) and MALLOC_CHECK_ is set (as it is in my environment).
2012-05-03Do not delete make check-abi symlist filesAndreas Jaeger2-0/+14
Do not remove the .symlist files and thus do not run objdump for each library etc if you repeat the make check command.
