From: Hannes Domani Date: Sun, 26 Apr 2020 13:28:46 +0000 (+0200) Subject: Fix array pretty formatter X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d642b6920b1a697da2e8fa2326cb773612a87f3f;p=binutils-gdb.git Fix array pretty formatter Currently, printing with array pretty formatting makes the output actually less readable than without: (gdb) p -array on -- {{1,2,3},{4,5,6}} $1 = { {1, 2, 3}, {4, 5, 6}} (gdb) p -array on -array-indexes on -- {{1,2,3},{4,5,6}} $2 = {[0] = {[0] = 1, [1] = 2, [2] = 3}, [1] = {[0] = 4, [1] = 5, [2] = 6}} These changes now also put the first element and the array end bracket on a new line, similar to the structure pretty formatter: (gdb) p -array on -- {{1,2,3},{4,5,6}} $1 = { { 1, 2, 3 }, { 4, 5, 6 } } (gdb) p -array on -array-indexes on -- {{1,2,3},{4,5,6}} $2 = { [0] = { [0] = 1, [1] = 2, [2] = 3 }, [1] = { [0] = 4, [1] = 5, [2] = 6 } } gdb/ChangeLog: 2020-04-29 Hannes Domani PR gdb/17320 * ada-valprint.c (val_print_packed_array_elements): Move array end bracket to new line.
