2014-05-20Add MIPS .module directivemfortune12-284/+376
gas/ * config/tc-mips.c (file_mips_opts_checked): New static global. (s_module): New static function. (file_ase): Remove. (mips_pseudo_table): Add .module handler. (mips_set_ase): Add opts argument and use instead of mips_opts. (md_assemble): Use file_mips_check_options. (md_parse_option): Update to use file_mips_opts instead of mips_opts. (mips_set_architecture): Delete function. Moved to... (mips_after_parse_args): Here. All logic now applies to file_mips_opts first and then copies the final state to mips_opts. Move error checking and defaults inference to mips_check_options and file_mips_check_options. (mips_check_options): New static function. Common option checking for command line, .module and .set. Use .module values in error messages instead of refering to command line options. (file_mips_check_options): New static function. A wrapper for mips_check_options with file_mips_opts. Updates BFD arch based on final options. (s_mipsset): Split into s_mipsset and parse_code_option. Settings supported by both .set and .module are moved to parse_code_option. Warnings and errors are kept in s_mipsset because when parse_code_option is used with s_module the warnings are deferred until code is generated. Any setting supporting 'default' value is kept in s_mipsset as it is not applicable to s_module. Inferred settings are also kept in s_mipsset as s_module does not infer any settings. Use mips_check_options. (parse_code_option): New static function derived from s_mipsset. (s_module): New static function that implements .module. Allows file level settings to be changed until code is generated. (s_cpload, s_cpsetup, s_cplocal): Use file_mips_check_options. (s_cprestore, s_cpreturn, s_cpadd, mips_address_bytes): Likewise.

2014-05-05Properly handle multiple opcode prefixesH.J. Lu10-21/+437
This patch updates multiple opcode prefix processing: 1. Always print prefix together with bad opcode. 2. Since the last seen segment register prefix is active, we only print the active segment register in the memory operand. 3. The 0xf2 and 0xf3 prefixes take precedence over the 0x66 prefix as the opcode prefix. Also the last of the 0xf2 and 0xf3 prefixes wins. 4.

2014-04-22Fix alignment for the first section frag on xtensaMax Filippov6-1/+28
Linking object files produced by partial linking with link-time relaxation enabled sometimes fails with the following error message: dangerous relocation: call8: misaligned call target: (.text.unlikely+0x63) This happens because no basic block with an XTENSA_PROP_ALIGN flag in the property table is generated for the first basic block, even if the .align directive is present. It was believed that the first frag alignment could be derived from the section alignment, but this was not implemented for the partial linking case: after partial linking first frag of a section may become not first, but no additional alignment frag is inserted before it. Basic block for such frag may be merged with previous basic block into extended basic block during relaxation pass losing its alignment restrictions. Fix this by always recording alignment for the first section frag. 2014-04-22 Max Filippov <jcmvbkbc@gmail.com> gas/ * config/tc-xtensa.c (xtensa_handle_align): record alignment for the first section frag. gas/testsuite/ * gas/xtensa/all.exp: Add test for the first section frag alignment. * gas/xtensa/first_frag_align.d: First section frag alignment expected dump. * gas/xtensa/first_frag_align.s: First section frag alignment test source.

2014-04-09gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEWAlan Modra51-325/+427
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION to TC_CONS_FIX_NEW via static variables.

2014-04-02Add checks for overfar branchesDJ Delorie2-2/+17
Check 8 and 16 bit PCREL fixes for overflow, since we bypass the later overflow checks in write.c. Direct relocs are left alone, as gcc has been known to take advantage of the silent overflows when comparing addresses to constant ranges.
2014-04-02This fixes an internal error in GAS, triggered by the test case reported in ↵Nick Clifton2-2/+13
PR 16765. The problem was that gcc was generating assembler with missing unwind directives in it, so that a gas_assert was being triggered. The patch replaces the assert with an error message. * config/tc-arm.c (create_unwind_entry): Report an error if an attempt to recreate an unwind directive is encountered.
