2018-11-08ipa-inline.c/tree-inline.c: port from fprintf to dump API (PR ipa/86395)David Malcolm26-124/+294
This patch ports various fprintf calls in the inlining code to using the dump API, using the %C format code for printing cgraph_node *. I focussed on the dump messages that seemed most significant to end-users; I didn't port all of the calls. Doing so makes this information appear in -fopt-info and in optimization records, rather than just in the dump_file. It also changes the affected dumpfile-dumps from being unconditional (assuming the dump_file is enabled) to being guarded by the MSG_* status. Hence various tests with dg-final scan-*-dump directives need to gain "-all" or "-optimized" suffixes to -fdump-ipa-inline. The use of %C throughout also slightly changes the dump format for several messages, e.g. changing: Inlining void inline_me(char*) into int main(int, char**). to: ../../src/gcc/testsuite/g++.dg/tree-ssa/inline-1.C:13:8: optimized: Inlining void inline_me(char*)/0 into int main(int, char**)/2. amongst other things adding "/order" suffixes to the cgraph node names. gcc/ChangeLog: PR ipa/86395 * doc/invoke.texi (-fdump-ipa-): Document the "-optimized", "-missed", "-note", and "-all" sub-options. * ipa-inline.c (caller_growth_limits): Port from fprintf to dump API.

2018-11-08Support %f in pp_formatDavid Malcolm7-0/+26
Numerous formatted messages from the inliner use %f, mostly as %f, but occasionally with length modifiers. This patch implements the simplest case of "%f" for pp_format (with no modifier support) to make it easier to port these messages from fprintf to dump_printf_loc. The selftest has an assertion that %f on 1.0 is printed as "1.000000". This comes from the host's sprintf, and I believe this is guaranteed by POSIX: "If the precision is missing, it shall be taken as 6". If this is an issue I can drop the selftest. gcc/c-family/ChangeLog: * c-format.c (gcc_dump_printf_char_table): Add entry for %f. gcc/ChangeLog: * pretty-print.c (pp_format): Handle %f. (selftest::test_pp_format): Add test of %f. * pretty-print.h (pp_double): New macro. gcc/testsuite/ChangeLog: * gcc.dg/format/gcc_diag-10.c: Add coverage for %f. From-SVN: r265919
2018-11-08dump_printf: add "%C" for dumping cgraph_node *David Malcolm8-50/+161
This patch implements support for %C in dump_printf for dumping cgraph_node *.

2018-11-08cgraph: add selftest::symbol_table_testDavid Malcolm5-0/+106
This patch adds a selftest fixture for overriding the "symtab" global, so that selftests involving symtab nodes can be isolated from each other: each selftest can have its own symbol_table instance.

2018-11-07Update libquadmath fmaq from glibc, fix nanq issues.Joseph Myers9-91/+93
This patch extends update-quadmath.py to update fmaq from glibc. The issue in that function was that quadmath-imp.h had a struct in a union with mant_high and mant_low fields (up to 64-bit) whereas glibc has mantissa0, mantissa1, mantissa2 and mantissa3 (up to 32-bit). The patch changes those fields to be the same as in glibc, moving printf / strtod code that also uses those fields back to closer to the glibc form. This allows fmaq to be updated automatically from glibc (which brings in at least one bug fix from glibc from 2015). nanq was also using the mant_high field name, and had other issues: it only partly initialized the union from which a value was returned, and setting mant_high to 1 meant a signaling NaN would be returned rather than a quiet NaN. This patch fixes those issues as part of updating it to use the changed interfaces (but does not fix the issue of not using the argument). Bootstrapped with no regressions on x86_64-pc-linux-gnu. * quadmath-imp.h (ieee854_float128): Use mantissa0, mantissa1, mantissa2 and mantissa3 fields instead of mant_high and mant_low. Change nan field to ieee_nan. * update-quadmath.py (update_sources): Also update fmaq.c. * math/nanq.c (nanq): Use ieee_nan field of union. Zero-initialize f. Set quiet_nan field. * printf/flt1282mpn.c, printf/printf_fphex.c, strtod/mpn2flt128.c, strtod/strtoflt128.c: Use mantissa0, mantissa1, mantissa2 and mantissa3 fields.
