Bug ID: 30725
Summary: severe objdump performance regression
Product: binutils
Version: 2.41
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: Stromeko at nexgo dot de
Target Milestone: ---
On Cygwin the performance of objdump has further degraded with 2.41. The
extraction of the debuginfo source files from the objects with "objdump -d -l"
that was already quite slow sees an additional 2× slowdown cs. the previous
version.
* cygport gcc install
2.39: 8763.607u 284.933s 29:14.38 515.7% 0+0k 0+0io 41005478pf+0w
2.40: 10122.687u 249.745s 31:29.71 548.8% 0+0k 0+0io 41382419pf+0w
2.41: 23065.196u 516.525s 1:02:40.22 627.1% 0+0k 0+0io 41348709pf+0w
The timing of install phase of gcc is dominated by the objdump invocation and
there mainly by the compiler executables (d21 usually takes the longest).
