== This Week ==
* TCWG-777 (3/10) - Fixed ICE with the patch - toolchain builds with the patch. - Sent patch to tcwg list for review - Investigating why combine fails to combine arm_andsi3_insn/arm_cmpsi_insn into zeroextractsi_compare0_scratch when the pass uses ud-chains to find def but works when def is found using ad-hoc way.
* TCWG-871 (4/10) - Getting familiar with firefox build system - LTO build lto/non-lto on x86 and arm (doc) - Figuring out how to resolve "plugin needed to handle lto object" error. tried the following: binutils configured with: --enable-plugin, --enable-lto gcc configured with: --enable-lto --with-ld-plugin=<just built ld> Doesn't appear to work.
* TCWG-835 (1/10) - Build failure with spec (PR67399)
* Misc (2/10) - Meetings - Looked at rtl dataflow (df.h and df*.c) and ree.c
