* arm: Fix addressing in optpld macroKyrill Tkachov2017-01-262-4/+4
| | | | | | | | | | | | | | | In patch b219285f873cc79361355938bd2a994957b4a6ef you have a syntax error in the PLD instruction. The syntax for the pld argument should be in square brackets as it's a memory address like so: pld [r1]. With your patch the newlib build fails for armv7-a targets. This patch fixes the build failures. Tested by making sure the newlib build completes successfully. 2016-01-26 Kyrylo Tkachov <kyrylo.tkachov@arm.com> * libc/machine/arm/strcpy.c (strcpy): Fix PLD assembly syntax. * libc/machine/arm/strlen-stub.c (strlen): Likewise.
* arm: Remove RETURN macroPat Pannuto2017-01-256-33/+23
| | | | | | | | | | | | | | LTO can re-order top-level assembly blocks, which can cause this macro definition to appear after its use (or not at all), causing compilation failures. On modern toolchains (armv4t+), assembly should write `bx lr` in all cases, and linkers will transparently convert them to `mov pc, lr`, allowing us to simply remove the macro. (source: https://groups.google.com/forum/#!topic/comp.sys.arm/3l7fVGX-Wug and verified empirically) For the armv4.S file, preserve this macro to maximize backwards compatibility.
* arm: Remove optpld macroPat Pannuto2017-01-253-18/+11
| | | | | | | | | | | LTO can re-order top-level assembly blocks, which can cause this macro definition to appear after its use (or not at all), causing compilation failures. As the macro has very few uses, simply removing it by inlining is a simple fix. n.b. one of the macro invocations in strlen-stub.c was already guarded by the relevant #define, so it is simply converted directly to a pld

* Prefix consistenly target-independent locks with __Thomas Preudhomme2017-01-252-11/+11
| | | | | | | | | | | | | | | | | | | Hi, With the patch to allow newlib's locking routine to be retargeted currently under discussion, we need to start thinking of locks as part of newlib's ABI since newlib depends on specific names being provided by the OS. This patch renames 2 locks so that they follow the same naming convention as other locks. It needs to be applied before the retargeting patch, while locks are still an internal consideration. Newlib builds successfully with this change. Ok for master branch? Best regards, Thomas
* nl_langinfo: Add NL_LOCALE_NAME macroEric Blake2017-01-202-1/+18
| | | | | | | | | | | | | | | | | | | | | Provide an extension NL_LOCALE_NAME() macro, with semantics matching glibc, which can be used as: nl_langinfo_l(NL_LOCALE_NAME(LC_MESSAGES), locale); to get back the locale string that locale was originally created with during newlocale(). This in turn allows a library (such as gettext) to determine what thread-local locale settings it has inherited from the main program without having to be told what parameters were passed to newlocale(), for less overall coupling between parts of the program. gnulib is set up to use the extension: https://lists.gnu.org/archive/html/bug-gnulib/2017-01/msg00129.html * libc/include/langinfo.h (NL_LOCALE_NAME): New macro * libc/locale/nl_langinfo.c (nl_langinfo_l): Expose locale names of a locale_t's category components.

* Add missing headers to fix implicit function defnsPat Pannuto2017-01-164-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few files were missing headers for memset/malloc, likely missed because the files don't directly call the functions, rather they come in via macros in libc/include/sys/reent.h: #define _REENT_CHECK(var, what, type, size, init) do { \ struct _reent *_r = (var); \ if (_r->what == NULL) { \ _r->what = (type)malloc(size); \ #define _REENT_CHECK_ASCTIME_BUF(var) \ _REENT_CHECK(var, _asctime_buf, char *, _REENT_ASCTIME_SIZE, \ memset((var)->_asctime_buf, 0, _REENT_ASCTIME_SIZE)) Without these fixes, implicit function signatures are provided, which gcc warns could cause aliasing issues down the line: ../../../../../../../newlib-2.5.0/newlib/libc/time/asctime.c:62:3: warning: type of 'memset' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: return value type mismatch _PTR _EXFUN(memset,(_PTR, int, size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: 'memset' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/string.h:29:7: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/time/asctime.c:62:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/time/lcltime.c:58:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used ../../../../../../../newlib-2.5.0/newlib/libc/string/strsignal.c:70:3: warning: type of 'malloc' does not match original declaration [-Wlto-type-mismatch] /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: return value type mismatch extern _PTR malloc _PARAMS ((size_t)); ^ /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: 'malloc' was previously declared here /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used Including the proper headers elminates the implicit function signatures and these warnings.

* Fix incorrect cast in nano mallocJoe Seymour2017-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in nano-mallocr.c, chunks of heap are represented in memory as a size (of type long), followed by some optional padding containing a negative offset to size, followed by the data area. get_chunk_from_ptr is responsible for taking a pointer to the data area (as returned by malloc) and finding the start of the chunk. It does this by assuming there is no padding and trying to read the size, if the size is negative then it uses that as an offset to find the true size. Crucially, it reads the padding area as a long. nano_malloc is responsible for populating the optional padding area. It does so by casting a pointer to an (int *) and writing the negative offset into it. This means that padding is being written as an int but read as a long. On msp430 an int is 2 bytes, while a long is 4 bytes. This means that 2 bytes are written to the padding, but 4 bytes are read from it: it has only been partially initialised. nano_malloc is the default malloc implementation for msp430. This patch changes the cast from (int *) to (long *). The change to nano_malloc has has been observed to fix a TI Energia project that had been malfunctioning because malloc was returning invalid addresses. The change to nano_memalign is based entirely on code inspection. I've built and tested as follows: Configured (gcc+newlib) with: --target=msp430-elf --enable-languages=c gcc testsuite variations: msp430-sim/-mcpu=msp430 msp430-sim/-mcpu=msp430x msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either msp430-sim/-mhwmult=none msp430-sim/-mhwmult=f5series My testing has shown no regressions, however I don't know if the gcc testsuite provides sufficient coverage for this patch? I don't have write access, so if this patch is acceptable after review, I would appreciate it if someone would commit it for me.

| | | | | | | | | | | | | | __sinit initialises some common file descriptors as line buffered and relies on the first users of such FDs to call __smakebuf_r. If __smakebuf_r realises there's no space for a buffer (malloc returns NULL), it makes them unbuffered. However, while setting the __SNBF bit, it doesn't clear the __SLBF bit in the flags. Depending on the order in which functions check buffering flags in the FD, sometime they assume it's line buffered (e.g. __sfvwrite_r), trashing application memory that's not really been allocated to them. This patch solves the problem by clearing the unbuffered/line buffered flag when setting the line buffered/unbuffered flag.

* Fix pdf build failure with texinfo 6.1.0Thomas Preudhomme2016-10-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, make pdf on Ubuntu 16.04 fail with: newlib/libc/libc.texinfo:9: Missing @endcsname inserted. After a lot of fiddling the reason appears to be the combination of concept and function index despite a lack of concept index entries. Arguably texinfo should not error in that case but here we are, newlib will fail to build its documentation on some systems because of this. Since libc.texinfo only contains function index entries this patch simply removes the combination of indices. It does the same for libm.texinfo which has concept index entries but no function index entries. Tested by running make pdf, make dvi, make info and make html successfully. libc.pdf appears to have only one index as expected. == Proposed commit message == Fix pdf build failure with texinfo 6.1.0 as provided in Ubuntu 16.04. Index combination in libc.texinfo and libm.texinfo fails because both file have only one type of index entries. Removing index combination is thus harmless and solves the problem. Is this ok for master? Best regards, Thomas
