Delay evaluation of alignment expressions in output sections git commit 702d16713 broke expressions using CONSTANT(COMMONPAGESIZE) in ALIGN or SUBALIGN of output section statements, because these optional fields were evaluated at script parse time and the patch in question delayed setting of config.commonpagesize. The right thing to do is keep the tree representation of those fields for later evaluation. PR 23571 * ldlang.h (section_alignment): Make it an expression tree. (subsection_alignment): Likewise. * ldlang.c (topower): Delete. (output_section_statement_newfunc): Adjust initialization. (init_os): Evaluate section_alignment. (lang_size_sections_1): Likewise. (size_input_section): Evaluate subsection_alignment. (lang_enter_output_section_statement): Don't evaluate here. (lang_new_phdr): Use exp_get_vma rather than exp_get_value_int. * ldexp.h (exp_get_value_int): Delete. (exp_get_power): Declare. * ldexp.c (exp_get_value_int): Delete. (exp_get_power): New function. * emultempl/pe.em (place_orphan): Build expression for section alignment. * emultempl/pep.em (place_orphan): Likewise. * testsuite/ld-scripts/pr23571.d, * testsuite/ld-scripts/pr23571.t: New test. * testsuite/ld-scripts/align.exp: Run it. 2018-08-26 00:53:38 -04:00			`SECTIONS`
