* frags.c (MAX_MEM_FOR_RS_ALIGN_CODE): Avoid signed integer overflow.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.

2019-04-25Speed up locview resolution with relaxable fragsAlexandre Oliva1-0/+55
Targets such as xtensa incur a much higher overhead to resolve location view numbers than e.g. x86, because the expressions used to compute view numbers cannot be resolved soon enough. Each view number is computed by incrementing the previous view, if they are both at the same address, or by resetting it to zero otherwise. If PV is the previous view number, PL is its location, and NL is the location of the next view, its number is computed by evaluating NV = !(NL > PL) * (PV + 1). set_or_check_view uses resolve_expression to decide whether portions of this expression can be simplified to constants. The (NL > PL) subexpression is one that can often be resolved to a constant, breaking chains of view number computations at instructions of nonzero length, but not after alignment that might be unnecessary. Alas, when nearly every frag ends with a relaxable instruction, frag_offset_fixed_p will correctly fail to determine a known offset between two unresolved addresses in neighboring frags, so the unresolved symbolic operation will be constructed and used in the computation of most view numbers. This results in very deep expressions. As view numbers get referenced in location view lists, each operand in the list goes through symbol_clone_if_forward_ref, which recurses on every subexpression. If each view number were to be referenced, this would exhibit O(n^2) behavior, where n is the depth of the view number expressions, i.e., the length of view number sequences without an early resolution that cuts the expression short. This patch enables address compares used by view numbering to be resolved even when exact offsets are not known, using new logic to determine when the location either remained the same or changed for sure, even with the possibility of relaxation. This enables most view number expressions to be resolved with a small, reasonable depth.

2019-02-10gas: Pass max_bytes to TC_FRAG_INITH.J. Lu1-1/+1
ommit 3ae729d5a4f63740ed9a778960b17c2912b0bbdd Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Mar 7 04:18:45 2018 -0800 x86: Rewrite NOP generation for fill and alignment increased MAX_MEM_FOR_RS_ALIGN_CODE to 4095 which resulted in increase of assembler time and memory usage by 5 times for inputs with many .p2align directives, which is typical for LTO output. This patch passes max_bytes to TC_FRAG_INIT so that MAX_MEM_FOR_RS_ALIGN_CODE can be set as needed and tracked by backend it so that HANDLE_ALIGN can check the maximum alignment for each rs_align_code frag.
