From 8c32dda686d2b964b08cc4614ba9c445039b3dd9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Thu, 23 Apr 2015 07:29:41 +0200 Subject: beam_validator: Stop validating the 'aligned' flag for binaries The run-time system stopped paying attention the 'aligned' flag in bit syntax construction and matching when bitstrings were introduced in language. The beam_asm compiler pass will crash if the 'aligned' flag is given in bit syntax instructions. beam_validator still validates the 'aligned' flag. Before 912fea0b712a (which removed the possibility to validate existing BEAM files), the 'aligned' flag could actually be encountered when validating a BEAM file. Since the validation of 'aligned' no longer serves any useful purpose, remove the validation code. --- .../test/beam_validator_SUITE_data/bin_aligned.S | 47 ---------------------- 1 file changed, 47 deletions(-) delete mode 100644 lib/compiler/test/beam_validator_SUITE_data/bin_aligned.S (limited to 'lib/compiler/test/beam_validator_SUITE_data/bin_aligned.S') diff --git a/lib/compiler/test/beam_validator_SUITE_data/bin_aligned.S b/lib/compiler/test/beam_validator_SUITE_data/bin_aligned.S deleted file mode 100644 index a59f7ccc03..0000000000 --- a/lib/compiler/test/beam_validator_SUITE_data/bin_aligned.S +++ /dev/null @@ -1,47 +0,0 @@ -{module, bin_aligned}. %% version = 0 - -{exports, [{decode,1},{module_info,0},{module_info,1}]}. - -{attributes, []}. - -{labels, 7}. - - -{function, decode, 1, 2}. - {label,1}. - {func_info,{atom,t},{atom,decode},1}. - {label,2}. - {move,{integer,1},{x,1}}. - {bif,size,{f,0},[{x,0}],{x,2}}. - {bs_add,{f,0},[{x,1},{x,2},1],{x,1}}. - {bs_init2,{f,0},{x,1},0,1,{field_flags,[]},{x,1}}. - {bs_put_integer,{f,0}, - {integer,3}, - 1, - {field_flags,[aligned,unsigned,big]}, - {integer,0}}. - {bs_put_binary,{f,0},{atom,all},8,{field_flags,[unsigned,big]},{x,0}}. - {bs_put_integer,{f,0}, - {integer,5}, - 1, - {field_flags,[unsigned,big,aligned]}, - {integer,0}}. - {move,{x,1},{x,0}}. - return. - - -{function, module_info, 0, 4}. - {label,3}. - {func_info,{atom,t},{atom,module_info},0}. - {label,4}. - {move,{atom,t},{x,0}}. - {call_ext_only,1,{extfunc,erlang,get_module_info,1}}. - - -{function, module_info, 1, 6}. - {label,5}. - {func_info,{atom,t},{atom,module_info},1}. - {label,6}. - {move,{x,0},{x,1}}. - {move,{atom,t},{x,0}}. - {call_ext_only,2,{extfunc,erlang,get_module_info,2}}. -- cgit v1.2.3
