We can't set flag_pie to the default when flag_pic == 0, which may be set by -fno-pic or -fno-PIC, since the default value of flag_pie is non-zero when GCC is configured with --enable-default-pie. We need to initialize flag_pic to -1 so that we can tell if -fpic, -fPIC, -fno-pic or -fno-PIC is used.

2015-11-17Extend tree-call-cdce to calls whose result is usedRichard Sandiford1-1/+1
For -fmath-errno, builtins.c currently expands calls to sqrt to: y = sqrt_optab (x); if (y != y) [ sqrt (x); or errno = EDOM; ] The drawbacks of this are: - the call to sqrt is protected by the result of the optab rather than the input. It would be better to check __builtin_isless (x, 0), like tree-call-cdce.c does. - the branch isn't exposed at the gimple level and so gets little high-level optimisation. - we do this for log too, but for log a zero input produces -inf rather than a NaN, and sets errno to ERANGE rather than EDOM. This patch moves the code to tree-call-cdce.c instead, with the optab operation being represented as an internal function. This means that we can use the existing argument-based range checks rather than the result-based checks and that we get more gimple optimisation of the branch. Previously the pass was only enabled by default at -O2 or above, but the old builtins.c code was enabled at -O. The patch therefore enables the pass at -O as well. The previous patch to cfgexpand.c handled cases where functions don't (or are assumed not to) set errno, so this patch makes the builtins.c code dead. Tested on x86_64-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabi and visium-elf (for the EDOM stuff). gcc/ * builtins.c (expand_errno_check, expand_builtin_mathfn) (expand_builtin_mathfn_2): Delete.

2015-10-01bb-reorder: Add -freorder-blocks-algorithm= and wire it upSegher Boessenkool1-1/+3
This adds an -freorder-blocks-algorithm=[simple|stc] flag, with "simple" as default. For -O2 and up (except -Os) it is switched to "stc" instead. Targets that never want STC can override this. This changes -freorder-blocks to be on at -O1 and up (was -O2 and up). In effect, the changes are for -O1 (which now gets "simple" instead of nothing), -Os (which now gets "simple" instead of "stc", since STC results in much bigger code), and for targets that wish to never use STC (not in this patch though). 2015-09-23 Segher Boessenkool <segher@kernel.crashing.org> * bb-reorder.c (reorder_basic_blocks): Use the algorithm selected with flag_reorder_blocks_algorithm. * common.opt (freorder-blocks-algorithm=): New flag.

specified. This patch unsets -freorder-blocks-and-partition when -fprofile-use is not specified. Function splitting was not actually being performed in that case, as probably_never_executed_bb_p does not distinguish any basic blocks as being cold vs hot when there is no profile data. Leaving it enabled, however, causes the assembly code generator to create (empty) cold sections and labels, leading to unnecessary size overhead. 2015-09-25 Teresa Johnson <tejohnson@google.com> * opts.c (finish_options): Unset -freorder-blocks-and-partition if not using profile.

2015-09-24fdiagnostics-color=never does not disable color for some diagnosticsManuel López-Ibáñez1-3/+4
Actually, I was trying to reject non-warning options as argument to -Werror=. However, the new test fails because -fdiagnostics-color=never is always placed by the driver after the warning options when calling the compiler proper. This patch prunes all -fdiagnostics-color from the command-line but the last one, which is moved to the first position. gcc/ChangeLog: 2015-09-24 Manuel López-Ibáñez <manu@gcc.gnu.org> PR driver/67640 * opts-common.c (prune_options): Discard all -fdiagnostics-color but the last one, which is moved to the front to be processed first. * opts.c (enable_warning_as_error): Reject options that do not control warnings. gcc/testsuite/ChangeLog: 2015-09-24 Manuel López-Ibáñez <manu@gcc.gnu.org> PR driver/67640 * gcc.dg/Werror-13.c: New test.

2015-01-30Always pass explicit location to fatal_error.Joseph Myers1-2/+3
The patch <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00698.html> adding an overload for fatal_error that passes an explicit location broke gcc.pot regeneration because xgettext cannot handle function overloads with the diagnostic string argument in different positions. As the desired direction is for all diagnostics to have explicit locations, this patch addresses the regression by removing the version of fatal_error that does not pass a location, passing explicit input_location everywhere (in the hope that those will incrementally be changed to other locations, much as with the addition of a location argument to pedwarn some time ago - a lot of cases aren't meaningfully associated with a source file so UNKNOWN_LOCATION may be better). Note that this patch does not attempt to fix any existing issues with these diagnostics (such as wrongly starting with capital letters or ending with '.' or '\n'); it just adds the input_location argument. Bootstrapped with no regressions for x86_64-unknown-linux-gnu (Go excluded). gcc: * diagnostic.c (fatal_error (const char *, ...)): Remove function. * diagnostic-core.h (fatal_error (const char *, ...)): Remove prototype. * toplev.h (init_asm_output): Update comment on use of UNKNOWN_LOCATION with fatal_error. * cgraph.c, collect-utils.c, collect2.c, config/arc/arc.c, config/arc/arc.md, config/avr/avr.c, config/c6x/c6x.h, config/darwin.c, config/host-darwin.c, config/i386/host-cygwin.c, config/i386/intelmic-mkoffload.c, config/nios2/nios2.c, config/nvptx/mkoffload.c, config/nvptx/nvptx.h, config/rs6000/host-darwin.c, config/rs6000/rs6000.c, config/s390/s390.c, gcc.c, gcov-io.h, gcov-tool.c, ggc-common.c, ggc-page.c, graph.c, ipa-inline-analysis.c, ipa-reference.c, lto-cgraph.c, lto-section-in.c, lto-streamer-in.c, lto-streamer.c, lto-wrapper.c, objc/objc-act.c, opts.c, passes.c, plugin.c, tlink.c, toplev.c, tree-streamer-in.c, varpool.c: All callers of fatal_error changed to pass input_location as first argument. gcc/c-family: * c-opts.c, c-pch.c, cppspec.c: All callers of fatal_error changed to pass input_location as first argument. gcc/cp: * class.c, except.c, parser.c, pt.c: All callers of fatal_error changed to pass input_location as first argument. gcc/fortran: * f95-lang.c, gfortranspec.c, trans-const.c, trans-expr.c: All callers of fatal_error changed to pass input_location as first argument. gcc/java: * class.c, expr.c, jcf-parse.c, jvspec.c: All callers of fatal_error changed to pass input_location as first argument. gcc/lto: * lto-object.c, lto-symtab.c, lto.c: All callers of fatal_error changed to pass input_location as first argument. libcc1: * plugin.cc: All callers of fatal_error changed to pass input_location as first argument.
