2022-03-28analyzer: ensure that we purge state when reusing a conjured_svalue [PR105087]David Malcolm12-27/+180
PR analyzer/105087 describes a false positive from -Wanalyzer-double-free in which the analyzer erroneously considers two successive inlined vasprintf calls to have allocated the same pointer. The root cause is that the result written back from vasprintf is a conjured_svalue, and that we normally purge state when reusing a conjured_svalue, but various places in the code were calling region_model_manager::get_or_create_conjured_svalue but failing to then call region_model::purge_state_involving on the result. This patch fixes things by moving responsibility for calling region_model::purge_state_involving into region_model_manager::get_or_create_conjured_svalue, so that it is always called when reusing a conjured_svalue, fixing the false positive. gcc/analyzer/ChangeLog: PR analyzer/105087 * analyzer.h (class conjured_purge): New forward decl. * region-model-asm.cc (region_model::on_asm_stmt): Add conjured_purge param to calls binding_cluster::on_asm and region_model_manager::get_or_create_conjured_svalue. * region-model-impl-calls.cc (call_details::get_or_create_conjured_svalue): Likewise for call to region_model_manager::get_or_create_conjured_svalue.

The top-level configure options --with-gmp-dir and --with-mpfr-dir were obsoleted and marked as "REMOVED" back in 2006.

2022-03-28c++: constrained template friend matching ICE [PR105064]Patrick Palka2-9/+16
Here during declaration matching for the two constrained template friends, we crash from maybe_substitute_reqs_for because the second friend doesn't yet have DECL_TEMPLATE_INFO set (we're being called indirectly from push_template_decl). As far as I can tell, this situation happens only when declaring a constrained template friend within a non-template class (as in the testcase), in which case the substitution would be a no-op anyway. So this patch rearranges maybe_substitute_reqs_for to gracefully handle missing DECL_TEMPLATE_INFO by just skipping the substitution. PR c++/105064 gcc/cp/ChangeLog: * constraint.cc (maybe_substitute_reqs_for): Don't assume DECL_TEMPLATE_INFO is available. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/concepts-friend9.C: New test.

2022-03-28c++: hash table ICE with variadic alias [PR105003]Jason Merrill4-36/+85
For PR104008 we thought it might be enough to keep strip_typedefs from removing this alias template specialization, but this PR demonstrates that other parts of the compiler also need to know to consider it dependent. So, this patch changes complex_alias_template_p to no longer consider template parameters used when their only use appears in a pack expansion, unless they are the parameter packs being expanded. To do that I also needed to change it to use cp_walk_tree instead of for_each_template_parm. It occurs to me that find_template_parameters should probably also use cp_walk_tree, but I'm not messing with that now.

2022-03-28gimple-fold: fix location of loads for memory ops [PR104308]David Malcolm3-1/+10
PR analyzer/104308 reports that when -Wanalyzer-use-of-uninitialized-value complains about certain memmove operations where the source is uninitialized, the diagnostic uses UNKNOWN_LOCATION: In function 'main': cc1: warning: use of uninitialized value '*(short unsigned int *)&s + 1' [CWE-457] [-Wanalyzer-use-of-uninitialized-value] 'main': event 1 | |pr104308.c:5:8: | 5 | char s[5]; /* { dg-message "region created on stack here" } */ | | ^ | | | | | (1) region created on stack here | 'main': event 2 | |cc1: | (2): use of uninitialized value '*(short unsigned int *)&s + 1' here | The issue is that gimple_fold_builtin_memory_op converts a memmove to: _3 = MEM <unsigned short> [(char * {ref-all})_1]; MEM <unsigned short> [(char * {ref-all})&s] = _3; but only sets the location of the 2nd stmt, not the 1st. Fixed thusly, giving: pr104308.c: In function 'main': pr104308.c:6:3: warning: use of uninitialized value '*(short unsigned int *)&s + 1' [CWE-457] [-Wanalyzer-use-of-uninitialized-value] 6 | memmove(s, s + 1, 2); /* { dg-warning "use of uninitialized value" } */ | ^~~~~~~~~~~~~~~~~~~~ 'main': events 1-2 | | 5 | char s[5]; /* { dg-message "region created on stack here" } */ | | ^ | | | | | (1) region created on stack here | 6 | memmove(s, s + 1, 2); /* { dg-warning "use of uninitialized value" } */ | | ~~~~~~~~~~~~~~~~~~~~ | | | | | (2) use of uninitialized value '*(short unsigned int *)&s + 1' here | One side-effect of this change is a change in part of the output of gcc.dg/uninit-40.c from: uninit-40.c:47:3: warning: ‘*(long unsigned int *)(&u[1][0][0])’ is used uninitialized [-Wuninitialized] 47 | __builtin_memcpy (&v[1], &u[1], sizeof (V)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ uninit-40.c:45:5: note: ‘*(long unsigned int *)(&u[1][0][0])’ was declared here 45 | V u[2], v[2]; | ^ to: uninit-40.c:47:3: warning: ‘u’ is used uninitialized [-Wuninitialized] 47 | __builtin_memcpy (&v[1], &u[1], sizeof (V)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ uninit-40.c:45:5: note: ‘u’ declared here 45 | V u[2], v[2]; | ^ What's happening is that pass "early_uninit"(29)'s call to maybe_warn_operand is guarded by this condition: 1051 else if (gimple_assign_load_p (stmt) 1052 && gimple_has_location (stmt)) Before the patch, the stmt: _3 = MEM <unsigned long> [(char * {ref-all})&u + 8B]; has no location, and so early_uninit skips this operand at line 1052 above. Later, pass "uninit"(217) tests the var_decl "u$8", and emits a warning for it. With the patch, the stmt has a location, and so early_uninit emits a warning for "u" and sets a NW_UNINIT warning suppression at that location. Later, pass "uninit"(217)'s test of "u$8" is rejected due to that per-location suppression of uninit warnings, from the earlier warning. gcc/ChangeLog: PR analyzer/104308 * gimple-fold.cc (gimple_fold_builtin_memory_op): When optimizing to loads then stores, set the location of the new load stmt. gcc/testsuite/ChangeLog: PR analyzer/104308 * gcc.dg/analyzer/pr104308.c: New test. * gcc.dg/uninit-40.c (foo): Update expression in expected message.

2022-03-26PR middle-end/104885: Fix ICE with large stack frame on powerpc64.Roger Sayle1-1/+2
My recent testcase for PR c++/84964.C stress tests the middle-end by attempting to pass a UINT_MAX sized structure on the stack. Although my fix to PR84964 avoids the ICE after sorry on x86_64 and similar targets, a related issue still exists on powerpc64 (and similar ACCUMULATE_OUTGOING_ARGS/ARGS_GROW_DOWNWARD targets) which don't issue a "sorry, unimplemented" message, but instead ICE elsewhere. After attempting several alternate fixes, the simplest solution is to just defensively check in mark_stack_region_used that the upper bound of the region lies within the allocated stack_usage_map array, which is of size highest_outgoing_arg_in_use. When this isn't the case, the code now follows the same path as for variable sized regions, and uses stack_usage_watermark rather than a map. 2022-03-26 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog PR middle-end/104885 * calls.cc (mark_stack_region_used): Check that the region is within the allocated size of stack_usage_map.
2022-03-26ecog: Return 1 from insn_invalid_p if REG_INC reg overlaps some stored reg ↵Jakub Jelinek2-0/+34
[PR103775] The following testcase ICEs on aarch64-linux with -g and assembles with a warning otherwise, because it emits ldrb w0,[x0,16]! instruction which sets the x0 register multiple times. Due to disabled DCE (from -Og) we end up before REE with: (insn 12 39 13 2 (set (reg:SI 1 x1 [orig:93 _2 ] [93]) (zero_extend:SI (mem/c:QI (pre_modify:DI (reg/f:DI 0 x0 [114]) (plus:DI (reg/f:DI 0 x0 [114]) (const_int 16 [0x10]))) [1 u128_1+0 S1 A128]))) "pr103775.c":5:35 117 {*zero_extendqisi2_aarch64} (expr_list:REG_INC (reg/f:DI 0 x0 [114]) (nil))) (insn 13 12 14 2 (set (reg:DI 0 x0 [orig:112 _2 ] [112]) (zero_extend:DI (reg:SI 1 x1 [orig:93 _2 ] [93]))) "pr103775.c":5:16 111 {*zero_extendsidi2_aarch64} (nil)) which is valid but not exactly efficient as x0 is dead after the insn that auto-increments it. REE turns it into: (insn 12 39 44 2 (set (reg:DI 0 x0) (zero_extend:DI (mem/c:QI (pre_modify:DI (reg/f:DI 0 x0 [114]) (plus:DI (reg/f:DI 0 x0 [114]) (const_int 16 [0x10]))) [1 u128_1+0 S1 A128]))) "pr103775.c":5:35 119 {*zero_extendqidi2_aarch64} (expr_list:REG_INC (reg/f:DI 0 x0 [114]) (nil))) (insn 44 12 14 2 (set (reg:DI 1 x1) (reg:DI 0 x0)) "pr103775.c":5:35 -1 (nil)) which is invalid because it sets x0 multiple times, one in SET_DEST of the PATTERN and once in PRE_MODIFY. As perhaps other passes than REE might suffer from it, IMHO it is better to reject this during change validation. 2022-03-26 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/103775 * recog.cc (check_invalid_inc_dec): New function. (insn_invalid_p): Return 1 if REG_INC operand overlaps any stored REGs. * gcc.dg/pr103775.c: New test.
