[Bug binutils/31283] New: windmc (s390x) fails with: parser: syntax error
https://sourceware.org/bugzilla/show_bug.cgi?id=31283
Bug ID: 31283
Summary: windmc (s390x) fails with: parser: syntax error
Product: binutils
Version: 2.43 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: rjones at redhat dot com
Target Milestone: ---
On s390x only (does not happen on i686, x86-64, aarch64, ppc64le).
"test.mc" is a file which contains only the character ";" which
is a comment character for this Windows language.
$ ./configure --target=x86_64-w64-mingw32
$ make
$ cat test.mc
;
$ ./binutils/windmc ./test.mc
In test.mc at line 1: parser: syntax error.
In test.mc at line 1: fatal: syntax error.
$ git rev-parse HEAD

The stack trace at the error message is:
Breakpoint 1, yyparse () at mcparse.y:80
80 | error { mc_fatal ("syntax error"); }
(gdb) bt
#0 yyparse () at mcparse.y:80

[Bug binutils/31283] windmc (s390x) fails with: parser: syntax error
https://sourceware.org/bugzilla/show_bug.cgi?id=31283 --- Comment #1 from Richard Jones --- The .mc parser converts the input from windows 1252 to UTF16-LE (note: little endian). Dumping out the UTF16-LE bytes on x86-64: 0x52f320: 0x3b0x000x0a0x000x000x00 ';' '\n' and on s390x: 0x11f75d8: 0x3b0x000x0a0x000x000x00 ';' '\n' they are the same, because they are both little endian. However the implementation of this inside binutils/windmc.c is as an array of unichar (unsigned short). On s390x which is big endian, the first character is read as 0x3b00 (15104): (gdb) frame 1 #1 0x010089c0 in mc_set_content (src=0x11f75d0) at ./mclex.c:52 52input_stream = input_stream_pos = unichar_dup (src); (gdb) print *src $1 = 15104 I don't see anywhere in windmc.c where the code bothers to think about endianness ... -- You are receiving this mail because: You are on the CC list for the bug.
