2014-09-23gcc-gdb-test.exp: Handle old GDB "short int" and "long int" types.Mark Wielaard3-0/+23
Old GDB might show short and long as short int and long int. This made gcc.dg/guality/const-volatile.c ans restrict.c fail on older GDBs. According to the patch that changed this in newer versions of GDB this was a bug: https://sourceware.org/ml/gdb-patches/2012-09/msg00455.html The patch transforms the types "short int" and "long int" coming from GDB to plain "short" and "long". And a variant has been added to the const-volatile.c testcase to make sure short and long long are handled correctly now with older GDB. gcc/testsuite/ChangeLog * lib/gcc-gdb-test.exp (gdb-test): Transform gdb types "short int" and "long int" to plain "short" and "long". * gcc.dg/guality/const-volatile.c (struct bar): New struct containing short and long long fields.

2014-09-23Remove LIBGCC2_LONG_DOUBLE_TYPE_SIZE target macro.Joseph Myers28-155/+84
This patch removes the target macro LIBGCC2_LONG_DOUBLE_TYPE_SIZE. After recent changes, this macro was used in two ways in libgcc: to determine the mode of long double in dfp-bit.h, and to determine whether a particular mode has excess precision for use in complex multiplication. The former is concerned specifically with long double: it relates to use of strtold for converting between decimal and binary floating point. This is replaced by comparing __LDBL_MANT_DIG__ with the appropriate __LIBGCC_*_MANT_DIG__ macro. The latter is replaced __LIBGCC_*_EXCESS_PRECISION__ predefined macros. Remarks: * Comparing (__LDBL_MANT_DIG__ == __LIBGCC_XF_MANT_DIG__) is more fragile than it looks; it's possible for XFmode to have 53-bit mantissa (TARGET_96_ROUND_53_LONG_DOUBLE, on FreeBSD and DragonFlyBSD 32-bit), in which case such a comparison would not distinguish XFmode and DFmode as possible modes for long double. Fortunately, no target supporting that form of XFmode also supports long double = double (but if some target did, we'd need e.g. an additional macro giving the exponent range of each mode). Furthermore, this code doesn't actually get used for x86 (or any other target with XFmode support), because x86 uses BID not DPD and BID has its own conversion code (which handles conversions for both XFmode and TFmode without needing to go via strtold). And FreeBSD and DragonFlyBSD aren't among the targets with DFP support. So while in principle this code is fragile and it's a deficiency that it can't support both XFmode and TFmode at once (something that can't be solved with the string conversion approach without libc having TS 18661 functions such as strtof128), all these issues should not be a problem in practice. * If other cases of excess precision are supported in future, the code for defining __LIBGCC_*_EXCESS_PRECISION__ may need updating. Although the most likely such cases might not actually involve excess precision for any mode used in libgcc - FLT_EVAL_METHOD being 32 to do _Float16 arithmetic on _Float32 should have the effect of _Complex _Float16 arithmetic using __mulsc3 and __divsc3, rather than currently nonexistent __mulhc3 and __divhc3 as in bug 63250 for ARM. * As has been noted in the context of simultaneous support for __float128 and __ibm128 on Power, the semantics of macros such as LONG_DOUBLE_TYPE_SIZE are problematic because they rely on a poorly-defined precision value for floating-point modes (which seems to be intended as the number of significant bits in the representation, e.g. 80 for XFmode which may be either 12 or 16 bytes) uniquely identifying a mode (although defining an arbitrarily different value for one of the modes you wish to distinguish may work as a hack). It would be cleaner to have a target hook that gives a machine mode directly for float, double and long double, rather than going via these precision values. By eliminating all use of these macros (FLOAT_TYPE_SIZE, DOUBLE_TYPE_SIZE, LONG_DOUBLE_TYPE_SIZE) from code built for the target, this patch facilitates such a conversion to a hook (which I suppose would take some suitable enum as an argument to identify which of the three types to return a mode for). (The issue of multiple type support for DFP conversions would apply in that Power case. <https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01084.html> doesn't seem to touch on it, but it would seem reasonable to punt on it initially as hard to fix. There would also be the issue of getting functions such as __powikf2, __mulkc3, __divkc3 defined, but that's rather easier to address.)

2014-09-22runtime: Mark runtime_goexit function as noinline.Ian Lance Taylor1-0/+1
If the compiler inlines this function into kickoff, it may reuse the TLS block address to load g. However, this is not necessarily correct, as the call to g->entry in kickoff may cause the TLS address to change. If the wrong value is loaded for g->status in runtime_goexit, it may cause a runtime panic. By marking the function as noinline we prevent the compiler from reusing the TLS address. From-SVN: r215484
