* Fix atexit logic to honor _ATEXIT_DYNAMIC_ALLOC setting.Jeff Johnston2015-12-212-0/+12
| | | | | | | | | | | | | If small reent is enabled (_REENT_SMALL is defined) then malloc() was used in __register_exitproc() even if user requested it to be disabled (_ATEXIT_DYNAMIC_ALLOC is defined).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file libgloss/rl78/write.c currently contains code which outputs \r when \n is seen. The code will then output the \n as well. This patch removes the bit of code that tests for \n and then outputs \r. I made this change to fix some failures in gdb.base/call-ar-st.exp. In that test, I see two carriage returns followed by a newline. One CR is output by the libgloss code. The other is output by the terminal driver. The total list of failures fixed (using the default rl78 multilib) are: FAIL: gdb.base/call-ar-st.exp: print print_double_array(double_array) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_char_array(char_array) (timeout) FAIL: gdb.base/call-ar-st.exp: continue to tbreak2 (timeout) FAIL: gdb.base/call-ar-st.exp: continuing to tbreak3 (timeout) FAIL: gdb.base/call-ar-st.exp: print print_double_array(array_d) (timeout) FAIL: gdb.base/call-ar-st.exp: continuing to tbreak4 (timeout) FAIL: gdb.base/call-ar-st.exp: print sum_array_print(10, *list1, *list2, *list3, *list4) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_small_structs (timeout) FAIL: gdb.base/call-ar-st.exp: print print_ten_doubles(123.456, 123.456, -0.12, -1.23, 343434.8, 89.098, 3.14, -5678.12345, -0.11111111, 216.97065) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_small_structs from print_long_arg_list (timeout) FAIL: gdb.base/call-ar-st.exp: print print_struct_rep(*struct1, *struct2, *struct3) (timeout) FAIL: gdb.base/dprintf.exp: call: printf: 1st dprintf (timeout) FAIL: gdb.base/dprintf.exp: call: printf: 2nd dprintf (timeout) FAIL: gdb.base/interrupt.exp: process is alive (the program exited) There are no regressions. libgloss/ChangeLog: * rl78/write.c (_write): Don't output CR when LF is encountered.

* Check for 64 FP instructions availability in libm before using themThomas Preud'homme2015-12-097-6/+16
| | | | | | | | | | | | Currently, double precision math functions in newlib/libm/machine/arm detect whether neon instructions can be used for double precision computation by checking the architecture version (>= 8) and the availability of floating-point instructions. However, these instructions would not be available if targeting fpv5-sp-d16 as the FPU, which by definition does not have 64bit float instructions. This patch adds a check that __ARM_FP advertises 64bit float instructions. * libm/machine/arm/s_ceil.c: Also check that 64bit FP instructions are available in the guard. * libm/machine/arm/s_floor.c: Likewise. * libm/machine/arm/s_nearbyint.c: Likewise. * libm/machine/arm/s_rint.c: Likewise. * libm/machine/arm/s_round.c: Likewise. * libm/machine/arm/s_trunc.c: Likewise.

* Introduce the 'usertemp' filesystem typeJohannes Schindelin2015-12-075-4/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * mount.cc (mount_info::from_fstab_line): Support mounting the current user's temp folder as /tmp/. This is particularly useful a feature when Cygwin's own files are write-protected. * pathnames.xml: document the new usertemp file system type Detailed explanation: In the context of Windows, there is a per-user directory for temporary files, by default specified via the environment variable %TEMP%. Let's allow to use that directory for our /tmp/ directory. With this patch, we introduce the special filesystem type "usertemp": By specifying none /tmp usertemp binary,posix=0 0 0 in /etc/fstab, the /tmp/ directory gets auto-mounted to the directory specified by the %TEMP% variable. This feature comes handy in particularly in scenarios where the administrator might want to write-protect the entire Cygwin directory yet still needs to allow users to write into the /tmp/ directory. This is the case in the context of Git for Windows, where the Cygwin (MSys2) root directory lives inside C:\Program Files and hence /tmp/ would not be writable otherwise.
