From: ali hagigat To: binutils@sourceware.org Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable X-IsSubscribed: yes Mailing-List: contact binutils-help@sourceware.org; run by ezmlm Precedence: bulk List-Id: List-Subscribe: List-Archive: List-Post: List-Help: , Sender: binutils-owner@sourceware.org X-SW-Source: 2011-05/txt/msg00138.txt.bz2 2.1 Enable Listings: =E2=80=98-a[cdhlns]=E2=80=99 Note if the assembler source is coming from the standard input (eg because it is being created by gcc and the =E2=80=98-pipe=E2=80=99 command line switch is being= used) then the listing will not contain any comments or preprocessor directives. This is because the listing code bu=EF=AC=80ers input source lines from stdin only after they have been preprocessed by the assembler. This reduces memory usage and makes the code more e=EF=AC=83cient. ------------------------------ I have copied part of the as manual in the above. What is the relationship of the standard input, -pipe, gcc and as? Please give a clear example for this part of GNU "as" manual.
