GNU-style: Label(B3:) hello.cc(102): error: expected a ")"

Hello,

I have a piece of GNU-style Inline asm syntax code as below -

---------
void (x,x,x,x,x)

"movq 174%rbp, %rcx \n\t"

"movq %rdi, %r9 \n\t"
"movq %rdx, %r8 \n\t"
"movslq %ecx, %r10 \n\t"

"xorl %edi, %edi \n\t"
"xorl %ecx, %ecx \n\t"
"xorl %eax, %eax \n\t"

"testq %r9, %r9 \n\t"
"jle B12 \n\t"

"movq %rdx, 56%rsp \n\t"

On compiling on Linux x86_64 using ICC-v11.0, I get below error messages for label B3 only as below, remaining all labels are fine -

-----

const int ntor )
^

compilation aborted for hello.cc (code 2)
make: *** [hello.o] Error 2

Queries:
(a) How to resolve above error messages for L#102?

(b) Since this section is a part from single file which has multiple C/C++ files as a multi-package; sin, cos & fmod operation has been used here. Since these "sin, cos & fmod" has been referred by multiple files by almost all files as seen from objdump of the orignal source code. Over here, how should I call this sin, cos & fmod?

Looking for some clue??

B3: is part of your asm syntax - I think it should be in "B3: nt" as well

yeah, the qoute has to be provided, Thanks

I tried using GCC-v4.4 alongwith Binutils -v 2.18.50.0.9, I get asm error messages alongwith some peculiar behaviour too as below. The complete file code ends with last line # 234 but the I get error messages with GCC-v4.4 as -

ro/include -Wall -O3 -g -O3 -MT hello.o -MD -MP -MF .deps/hello.Tpo -c -o hello.o hello.cc
hello.cc: Assembler messages:

hello.cc:298: Error: bad register name `%3'

The above line numbers are not present in the file as the file ends with last line number being 234.

Should I conclude that the assembly statements which has been written for this Inline GNU-syntax asm code are not valid 64-bit asm.

But I got the same .S as an output file when doing "icpc -g -O3 -S hello.cc -fasm-blocks".

Below (Reply#3) is the snapshot with ICC-v11.0 on Linux x86_64.

Intel C++ Compiler-v11.0 gives me below error messages -

There is asm error messages difference (Reply#2 & Reply#3) generated by GCC-v4.4 (alongwith Binutils v-2.18.50.0.9) & ICC-v11.0. I am not sure which Binutils version ICC-v11.0 uses.

Also, the line# as shown in asm error messages (58, 68, 69, 76, 88 & 91) doesn't match the Inline-asm code within hello.cc.

I made all above issues and errors resolved,the GNU-syntax Inline asm code is working fine now.TX ISN
