[PATCH, aarch64 0/4] Add movprfx patterns and alternatives

These don't fire very often, but at least a few times within the testsuite. Enough to test my qemu implementation of the insns. r~ Richard Henderson (4): aarch64: Add movprfx alternatives for unpredicated patterns aarch64: Remove predicate from inside SVE_COND_FP_BINARY aarch64: Add movp

[committed] Reinstate dump_generic_expr_loc

In r262149 ("Introduce dump_location_t", aka c309657f69df19eaa590b6650acf4d3bea9ac9e6), I removed dump_generic_expr_loc from dumpfile.h/c as it was unused in the source tree. It looks like this was overzealous of me, as Richard wants to use it in "Re: [14/n] PR85694: Rework overwidening detectio

abstract ABS_EXPR code for ranges into separate function

Boy those extract_range_from_*_expr functions are huge. OK to move the ABS_EXPR code into its own function? Tested on x86-64 Linux. Aldy commit 1e0dd52b909722e9387a34ef546fc308c68dac23 Author: Aldy Hernandez Date: Fri Jun 29 20:12:36 2018 +0200 * tree-vrp.c (extract_range_from_u

[testsuite, committed] Fix get-absolute-line error handling

Hi, in factoring out get-absolute-line, I made a typo in a variable name used in an error message, which causes a tcl ERROR when the error condition is triggered. Fixed by this patch. This tcl ERROR didn't show up unless the error message was triggered by an error condition, which normally doesn

[testsuite/guality, committed] Use relative line numbers in vla-1.c

Hi, this patch replaces absolute with relative line numbers in guality/vla-1.c. The test-case has a line: ... $ cat -n gcc/testsuite/gcc.dg/guality/vla-1.c 17return a[0]; /* { dg-final { gdb-test 17 "sizeof (a)" "6" } } */ ... which corresponds to relative line number '.'. This

[PATCH, committed] Add -mgnu-asm to pdp11 target, change -mdec-asm

The pdp11 target has long had -mdec-asm which was documented to generate DEC compatible assembly language output but actually produces GNU assembler output. This patch adds -mgnu-asm to do what -mdec-asm used to do, and -mdec-asm now does produces output acceptable to DEC Macro-11. Committed.

Re: Limit Debug mode impact: overload __niter_base

    Here is a new proposal between yours and mine.     It is still adding a function to wrap what __niter_base unwrap, I called it __nwrap_iter for this reason. But it takes advantage of knowing that __niter_base will only unwrap random access iterator to use an expression to that will do the

[testsuite/guality, committed] Use @main as bp loc instead of line nrs in const-volatile.c

Hi, this patch replaces the absolute line numbers used in gdb-test in guality testcase const-volatile.c. First there's line number 50, which used to point at the start of main: ... 47 int 48 main (int argc, char **argv) 49 { 50score as = argc; ... but has drifted in time to
