[committed] Further distinguish between length for warnings vs length for codegen/optimization

This is the second behavior changing hunk of Martin's work. In this patch we improve the distinction between maxbound/maxlen in get_range_strlen. This throttles several of the boundry crossing issues with string length range computations by allowing us to distinguish better between a length for

[committed] Fix a couple minor problems with string length range computations

So the first of probably 3 patches to fix issues with string length computations now that the underlying infrastructure is in place. Like the prior patches, this is primarily Martin's work. My contribution has been to break it down into more manageable hunks. In this patch we change the

[PATCH,Fortran] Suppress unclassifiable statement error message

Due to the nuances of issuing error messages with ieee_selected_real_kind when used in an initialization expression, it became painfully obvious that gfortran will often issue an "Unclassifiable statement" error as a run-on error. I tried to make the "Unclassifiable ..." error a fatal error, but

[PATCH] ARM: fix -masm-syntax-unified (PR88648)

This allows to use unified asm syntax when compiling for the ARM instruction. This matches documentation and seems what the initial patch was intended doing when the flag got added. --- gcc/config/arm/arm.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gcc/config/arm/arm.c

Hello world, first of all, Happy New Year to everybody! In 2018, we fixed 333 bugs, an average of 0.91 per day. Not bad at all. Here is a first contribution towards reaching something similar, or even better, for 2019. It is a rather straightforward patch which adds a missing warning for

[committed] API change for internal get_range_strlen

This changes the internal API for get_range_strlen to use c_strlen_data rather than passing in the tree[2] for min/max length plus the tree * for the nonstr object. It also initializes the "maxbound" member within the c_strlen data object. The publicly visible interface to get_range_strlen

Re: Fix unresolved tests I introduced into g++.dg/lto

Hi, this patch does housekeeping for ipa directory. I still plan to port more of the non-LTO testcases into LTO variant (to be sure LTO devirtualization works same way as non-LTO) but will do that after handling bugs and other higher priority tasks. Honza * g++.dg/ipa/devirt-36.C: Add

Hi, this patch fixes the unresolved tests i accidentally introduced to lto directory. I ended up droping the tree scan for now as I do not know how to get that working and both testcases also tests runtime. Honza * g++.dg/lto/devirt-13_0.C: Drop broken scan of ssa dump. *
