 2.12.1.7 Linux Alpha Notes
 ..........................
 
 We have tested MySQL 5.0 on Alpha with our benchmarks and test suite,
 and it appears to work well.
 
 We currently build the MySQL binary packages on SuSE Linux 7.0 for AXP,
 kernel 2.4.4-SMP, Compaq C compiler (V6.2-505) and Compaq C++ compiler
 (V6.3-006) on a Compaq DS20 machine with an Alpha EV6 processor.
 
 You can find the preceding compilers at
 `http://www.support.compaq.com/alpha-tools/'. By using these compilers
 rather than `gcc', we get about 9-14% better MySQL performance.
 
 For MySQL on Alpha, we use the -arch generic flag to our compile
 options, which ensures that the binary runs on all Alpha processors. We
 also compile statically to avoid library problems. The `configure'
 command looks like this:
 
      CC=ccc CFLAGS="-fast -arch generic" CXX=cxx \
      CXXFLAGS="-fast -arch generic -noexceptions -nortti" \
      ./configure --prefix=/usr/local/mysql --disable-shared \
          --with-extra-charsets=complex --enable-thread-safe-client \
          --with-mysqld-ldflags=-non_shared --with-client-ldflags=-non_shared
 
 If you want to use `egcs', the following `configure' line worked for us:
 
      CFLAGS="-O3 -fomit-frame-pointer" CXX=gcc \
      CXXFLAGS="-O3 -fomit-frame-pointer -felide-constructors \
          -fno-exceptions -fno-rtti" \
      ./configure --prefix=/usr/local/mysql --disable-shared
 
 Some known problems when running MySQL on Linux-Alpha:
 
    * Debugging threaded applications like MySQL does not work with `gdb
      4.18'. You should use `gdb' 5.1 instead.
 
    * If you try linking `mysqld' statically when using `gcc', the
      resulting image dumps core at startup time. In other words, _do
      not_ use -with-mysqld-ldflags=-all-static with `gcc'.
