This wiki page tells you some steps and tips to build Mozilla Product using Intel C/C++ Compiler.

---

• Step 0 Prepare Build Environment
• Step 1 Patch start-msvc .bat
• Step 2 Prepare .mozconfig
• Step 3 Modify Mozilla Makefile
• Step 4 Build
• Step 5 Make installer
• Optimization Method
• Supplement & Postscript

Step 0 Prepare Build Environment

The compiler and SDKs which I use are below.

Mozilla-build
官方链接

Visual C/C++ Compiler
Microsoft Visual Studio 2010 SP1

Windows SDK
Microsoft Windows SDK for Windows 7 and .NET Framework 4

DirectX SDK
Microsoft DirectX SDK (June 2010)

Intel C/C++ Compiler
12 update 10/13 beta update1

Step 1 Patch start-msvc.bat

The patch is similar to it below.

Of cource, you can create new file called start-icc.bat analogously.

X64 build bat is similar.

Step 2 Prepare .mozconfig

Put .mozconfig on the source code tree's Top-level directory.

If you use ICC 13 beta update1, then apply the similar patches below:

4) GUI bug

There are two forms of the bug:

• Click Option - Click OK - Close Firefox - Open Firefox - Empty GUI framework
• startupCache issue - Empty GUI framework. see the link

nsBinaryStream.cpp will cause wrong code when using -Qax switch

5) Improve compatibility (Optional)

Mozilla use -MD to build code by default, which will link the dynamic Intel LibMath, which can reduce some memory, this may cause some extensions not to work.

So if you wan to static link Intel LibMath, you can use the similar patch:

Step 4 Build

Assume you put the source code to e:\mozilla\mozilla-release .

Open mozilla msys bash

cd /e/mozilla/mozilla-release
make -f client.mk build

Step 5 Make installer

cd /e/mozilla/obju-icc
make installer

Then the installer will be in e:/mozilla/obju-vc/dist/install/sea .

Optimization Method

The methods involved below can be used at the same time.

1 Build BetterPGO

1) PGO bug workaround

Intel Compiler has some PGO bugs, may cause some crashes or abnormal phenomena, you can refer to the patches below:

2) Build pgo-gen

Modify .mozconfig section

ac_add_options --enable-optimize="-O2 -fp:precise -Qprof-gen -Qprof-dire:/mozilla/iccpgo"

make -f client.mk build

3) Generate PGO information

You can enter into <obj>/dist/bin, run firefox.exe and some PGO tests, close it.

4) Build pgo-use

Modify .mozconfig related section

ac_add_options --enable-optimize="-O2 -fp:precise -Qprof-use -Qprof-dire:/mozilla/iccpgo"

make -f client.mk build

2 Some Intel C/C++ Compiler options

-fp:precise

Improve the float caculation precision, if you don't want to use the patches above when using -fp:fast, you can use the switch.

-arch:SSE2 or -arch:SSE3

In general, all new cpu support SSE2, most support SSE3 ( especially Intel CPU).

-Qipo

Great switch, but make build process time very very long, and build process will need very much more memory. You can use -Qipo128 or -Qipo256 to improve the memory issue when linking.

-QaxSSE2,SSE3,SSSE3,SSE4.1,SSE4.2,AVX,CORE-AVX2,CORE-AVX-I

Invalid for AMD CPU, but may improve some performance on Intel CPU.

Note

If you use -Qax and -arch at a time, make sure put -arch after -Qax.

-O3

If you feel -O3 not safe, you can use -O2 -Qftz .

Some other switches

---

Supplement & Postscript

2012.6.5 security module can't be built using -O3 and -Qipo, which all cause crash.

Hi xunxun, Here are some more bugs I have found while compiling with ICC that you can add to your wiki:

CheckedInt?.h bug – fixed, will most likely be introduced into a much later version of FF (Intel has also been made aware of it and they said they’ve submitted it to their developers).

Compiling with jemalloc results in crashing WebGL module, to which your patch has to be used. Using standard malloc does not cause this.

In Firefox 15.0 & 15.0.1 the GUI bug has returned but in a different form but can be solved by your previous patch.

Using the fix for the GUI bug results in not being able to use pymake to compile.
