--- Comment #14 from Stefan Maksimovic <stefan.maksimo...@rt-rk.com> --- Created attachment 126546 --> https://bugs.kde.org/attachment.cgi?id=126546&action=edit branch special case patch Another update: Analyzing the mips and the x86 debug output side by side we noticed the following: The fallthrough blocks in the main function differ by x86 having an unconditional jump, which when translated to IR results in a single PUT(PC) instruction. Mips on the other hand uses a conditional branch instruction with parameters set so as to always take one of the two paths, making the jump effectively unconditional. By using a conditional branch a conditional PUT(PC) was generated in the IR which enabled the &&-transform to take place, resulting in the outcome described in previous comments. Attached patch modifies this special case of the branch instruction by not generating conditional PUTs to PC. Having applied this change the &&-transform does not take place in the main function, much like in the x86 case. This fixes a number of failing tests on our side. -- You are receiving this mail because: You are watching all bug changes.
